Certifi: Python SSL Certificates
================================
Certifi provides Mozilla's carefully curated collection of Root Certificates for
validating the trustworthiness of SSL certificates while verifying the identity
of TLS hosts. It has been extracted from the `Requests`_ project.
Installation
------------
``certifi`` is available on PyPI. Simply install it with ``pip``::
$ pip install certifi
Usage
-----
To reference the installed certificate authority (CA) bundle, you can use the
built-in function::
>>> import certifi
>>> certifi.where()
'/usr/local/lib/python3.7/site-packages/certifi/cacert.pem'
Or from the command line::
$ python -m certifi
/usr/local/lib/python3.7/site-packages/certifi/cacert.pem
Enjoy!
.. _`Requests`: https://requests.readthedocs.io/en/master/
Addition/Removal of Certificates
--------------------------------
Certifi does not support any addition/removal or other modification of the
CA trust store content. This project is intended to provide a reliable and
highly portable root of trust to python deployments. Look to upstream projects
for methods to use alternate trust.

This package contains a modified version of ca-bundle.crt:
ca-bundle.crt -- Bundle of CA Root Certificates
This is a bundle of X.509 certificates of public Certificate Authorities
(CA). These were automatically extracted from Mozilla's root certificates
file (certdata.txt). This file can be found in the mozilla source tree:
https://hg.mozilla.org/mozilla-central/file/tip/security/nss/lib/ckfw/builtins/certdata.txt
It contains the certificates in PEM format and therefore
can be directly used with curl / libcurl / php_curl, or with
an Apache+mod_ssl webserver for SSL client authentication.
Just configure this file as the SSLCACertificateFile.#

## ⚡ Performance
This package offer better performance than its counterpart Chardet. Here are some numbers.
| Package | Accuracy | Mean per file (ms) | File per sec (est) |
|-----------------------------------------------|:--------:|:------------------:|:------------------:|
| [chardet](https://github.com/chardet/chardet) | 86 % | 63 ms | 16 file/sec |
| charset-normalizer | **98 %** | **10 ms** | 100 file/sec |
| Package | 99th percentile | 95th percentile | 50th percentile |
|-----------------------------------------------|:---------------:|:---------------:|:---------------:|
| [chardet](https://github.com/chardet/chardet) | 265 ms | 71 ms | 7 ms |
| charset-normalizer | 100 ms | 50 ms | 5 ms |
_updated as of december 2024 using CPython 3.12_
Chardet's performance on larger file (1MB+) are very poor. Expect huge difference on large payload.
> Stats are generated using 400+ files using default parameters. More details on used files, see GHA workflows.
> And yes, these results might change at any time. The dataset can be updated to include more files.
> The actual delays heavily depends on your CPU capabilities. The factors should remain the same.
> Keep in mind that the stats are generous and that Chardet accuracy vs our is measured using Chardet initial capability
> (e.g. Supported Encoding) Challenge-them if you want.
## ✨ Installation
Using pip:
```sh
pip install charset-normalizer -U
```
## 🚀 Basic Usage
### CLI
This package comes with a CLI.
```
usage: normalizer [-h] [-v] [-a] [-n] [-m] [-r] [-f] [-t THRESHOLD]
file [file ...]
The Real First Universal Charset Detector. Discover originating encoding used
on text file. Normalize text to unicode.
positional arguments:
files File(s) to be analysed
optional arguments:
-h, --help show this help message and exit
-v, --verbose Display complementary information about file if any.
Stdout will contain logs about the detection process.
-a, --with-alternative
Output complementary possibilities if any. Top-level
JSON WILL be a list.
-n, --normalize Permit to normalize input file. If not set, program
does not write anything.
-m, --minimal Only output the charset detected to STDOUT. Disabling
JSON output.
-r, --replace Replace file when trying to normalize it instead of
creating a new one.
-f, --force Replace file without asking if you are sure, use this
flag with caution.
-t THRESHOLD, --threshold THRESHOLD
Define a custom maximum amount of chaos allowed in
decoded content. 0. <= chaos <= 1.
--version Show version information and exit.
```
```bash
normalizer ./data/sample.1.fr.srt
```
or
```bash
python -m charset_normalizer ./data/sample.1.fr.srt
```
🎉 Since version 1.4.0 the CLI produce easily usable stdout result in JSON format.
```json
{
"path": "/home/default/projects/charset_normalizer/data/sample.1.fr.srt",
"encoding": "cp1252",
"encoding_aliases": [
"1252",
"windows_1252"
],
"alternative_encodings": [
"cp1254",
"cp1256",
"cp1258",
"iso8859_14",
"iso8859_15",
"iso8859_16",
"iso8859_3",
"iso8859_9",
"latin_1",
"mbcs"
],
"language": "French",
"alphabets": [
"Basic Latin",
"Latin-1 Supplement"
],
"has_sig_or_bom": false,
"chaos": 0.149,
"coherence": 97.152,
"unicode_path": null,
"is_preferred": true
}
```
### Python
*Just print out normalized text*
```python
from charset_normalizer import from_path
results = from_path('./my_subtitle.srt')
print(str(results.best()))
```
*Upgrade your code without effort*
```python
from charset_normalizer import detect
```
The above code will behave the same as **chardet**. We ensure that we offer the best (reasonable) BC result possible.
See the docs for advanced usage : [readthedocs.io](https://charset-normalizer.readthedocs.io/en/latest/)
## 😇 Why
When I started using Chardet, I noticed that it was not suited to my expectations, and I wanted to propose a
reliable alternative using a completely different method. Also! I never back down on a good challenge!
I **don't care** about the **originating charset** encoding, because **two different tables** can
produce **two identical rendered string.**
What I want is to get readable text, the best I can.
In a way, **I'm brute forcing text decoding.** How cool is that ? 😎
Don't confuse package **ftfy** with charset-normalizer or chardet. ftfy goal is to repair Unicode string whereas charset-normalizer to convert raw file in unknown encoding to unicode.
## 🍰 How
- Discard all charset encoding table that could not fit the binary content.
- Measure noise, or the mess once opened (by chunks) with a corresponding charset encoding.
- Extract matches with the lowest mess detected.
- Additionally, we measure coherence / probe for a language.
**Wait a minute**, what is noise/mess and coherence according to **YOU ?**
*Noise :* I opened hundred of text files, **written by humans**, with the wrong encoding table. **I observed**, then
**I established** some ground rules about **what is obvious** when **it seems like** a mess (aka. defining noise in rendered text).
I know that my interpretation of what is noise is probably incomplete, feel free to contribute in order to
improve or rewrite it.
*Coherence :* For each language there is on earth, we have computed ranked letter appearance occurrences (the best we can). So I thought
that intel is worth something here. So I use those records against decoded text to check if I can detect intelligent design.
## ⚡ Known limitations
- Language detection is unreliable when text contains two or more languages sharing identical letters. (eg. HTML (english tags) + Turkish content (Sharing Latin characters))
- Every charset detector heavily depends on sufficient content. In common cases, do not bother run detection on very tiny content.
## ⚠️ About Python EOLs
**If you are running:**
- Python >=2.7,<3.5: Unsupported
- Python 3.5: charset-normalizer < 2.1
- Python 3.6: charset-normalizer < 3.1
- Python 3.7: charset-normalizer < 4.0
Upgrade your Python interpreter as soon as possible.

"""
Charset-Normalizer
~~~~~~~~~~~~~~
The Real First Universal Charset Detector.
A library that helps you read text from an unknown charset encoding.
Motivated by chardet, This package is trying to resolve the issue by taking a new approach.
All IANA character set names for which the Python core library provides codecs are supported.
Basic usage:
>>> from charset_normalizer import from_bytes
>>> results = from_bytes('Bсеки човек има право на образование. Oбразованието!'.encode('utf_8'))
>>> best_guess = results.best()
>>> str(best_guess)
'Bсеки човек има право на образование. Oбразованието!'
Others methods and usages are available - see the full documentation
at <https://github.com/Ousret/charset_normalizer>.

Given a raw bytes sequence, return the best possibles charset usable to render str objects.
If there is no results, it is a strong indicator that the source is binary/not text.
By default, the process will extract 5 blocks of 512o each to assess the mess and coherence of a given sequence.
And will give up a particular code page after 20% of measured mess. Those criteria are customizable at will.
The preemptive behavior DOES NOT replace the traditional detection workflow, it prioritize a particular code page
but never take it for granted. Can improve the performance.
You may want to focus your attention to some code page or/and not others, use cp_isolation and cp_exclusion for that
purpose.
This function will strip the SIG in the payload/sequence every time except on UTF-16, UTF-32.
By default the library does not setup any handler other than the NullHandler, if you choose to set the 'explain'
toggle to True it will alter the logger configuration to add a StreamHandler that is suitable for debugging.
Custom logging format and handler can be set manually.

# Requests
**Requests** is a simple, yet elegant, HTTP library.
```python
>>> import requests
>>> r = requests.get('https://httpbin.org/basic-auth/user/pass', auth=('user', 'pass'))
>>> r.status_code
200
>>> r.headers['content-type']
'application/json; charset=utf8'
>>> r.encoding
'utf-8'
>>> r.text
'{"authenticated": true, ...'
>>> r.json()
{'authenticated': True, ...}
```
Requests allows you to send HTTP/1.1 requests extremely easily. There’s no need to manually add query strings to your URLs, or to form-encode your `PUT` & `POST` data — but nowadays, just use the `json` method!
Requests is one of the most downloaded Python packages today, pulling in around `30M downloads / week`— according to GitHub, Requests is currently [depended upon](https://github.com/psf/requests/network/dependents?package_id=UGFja2FnZS01NzA4OTExNg%3D%3D) by `1,000,000+` repositories. You may certainly put your trust in this code.
[![Downloads](https://static.pepy.tech/badge/requests/month)](https://pepy.tech/project/requests)

## API Reference and User Guide available on [Read the Docs](https://requests.readthedocs.io)
[![Read the Docs](https://raw.githubusercontent.com/psf/requests/main/ext/ss.png)](https://requests.readthedocs.io)
## Cloning the repository
When cloning the Requests repository, you may need to add the `-c
fetch.fsck.badTimezone=ignore` flag to avoid an error about a bad commit timestamp (see
[this issue](https://github.com/psf/requests/issues/2690) for more background):
```shell
git clone -c fetch.fsck.badTimezone=ignore https://github.com/psf/requests.git
```
You can also apply this setting to your global Git config:
```shell
git config --global fetch.fsck.badTimezone ignore
```

Requests HTTP Library
~~~~~~~~~~~~~~~~~~~~~
Requests is an HTTP library, written in Python, for human beings.
Basic GET usage:
>>> import requests
>>> r = requests.get('https://www.python.org')
>>> r.status_code
200
>>> b'Python is a programming language' in r.content
True
... or POST:
>>> payload = dict(key1='value1', key2='value2')
>>> r = requests.post('https://httpbin.org/post', data=payload)
>>> print(r.text)
{
...
"form": {
"key1": "value1",
"key2": "value2"
},
...
}
The other HTTP methods are supported - see `requests.api`. Full documentation
is at <https://requests.readthedocs.io>.

The SSL related pool key arguments are not consistently set. As of
this writing, use the following to determine what keys may be in that
dictionary:
* If ``verify`` is ``True``, ``"ssl_context"`` will be set and will be the
default Requests SSL Context
* If ``verify`` is ``False``, ``"ssl_context"`` will not be set but
``"cert_reqs"`` will be set
* If ``verify`` is a string, (i.e., it is a user-specified trust bundle)
``"ca_certs"`` will be set if the string is not a directory recognized
by :py:func:`os.path.isdir`, otherwise ``"ca_cert_dir"`` will be
set.
* If ``"cert"`` is specified, ``"cert_file"`` will always be set. If
``"cert"`` is a tuple with a second item, ``"key_file"`` will also
be present
To override these settings, one may subclass this class, call this
method and use the above logic to change parameters as desired. For
example, if one wishes to use a custom :py:class:`ssl.SSLContext` one
must both set ``"ssl_context"`` and based on what else they require,

``keys()``, ``items()``, ``iterkeys()``, and ``iteritems()``
will contain case-sensitive keys. However, querying and contains
testing is case insensitive::
cid = CaseInsensitiveDict()
cid['Accept'] = 'application/json'
cid['aCCEPT'] == 'application/json' # True
list(cid) == ['Accept'] # True
For example, ``headers['content-encoding']`` will return the
value of a ``'Content-Encoding'`` response header, regardless
of how the header name was originally stored.
If the constructor, ``.update``, or equality comparison
operations are given keys that have equal ``.lower()``s, the
behavior is undefined.

# Stripe Python Library
[![pypi](https://img.shields.io/pypi/v/stripe.svg)](https://pypi.python.org/pypi/stripe)
[![Build Status](https://github.com/stripe/stripe-python/actions/workflows/ci.yml/badge.svg?branch=master)](https://github.com/stripe/stripe-python/actions?query=branch%3Amaster)
The Stripe Python library provides convenient access to the Stripe API from
applications written in the Python language. It includes a pre-defined set of
classes for API resources that initialize themselves dynamically from API
responses which makes it compatible with a wide range of versions of the Stripe
API.
## API Documentation
See the [Python API docs](https://stripe.com/docs/api?lang=python).
## Installation
This package is available on PyPI:
```sh
pip install --upgrade stripe
```
Alternatively, install from source with:
```sh
python -m pip install .
```
### Requirements
Per our [Language Version Support Policy](https://docs.stripe.com/sdks/versioning?lang=python#stripe-sdk-language-version-support-policy), we currently support **Python 3.7+**.
Support for Python 3.7 and 3.8 is deprecated and will be removed in an upcoming major version. Read more and see the full schedule in the docs: https://docs.stripe.com/sdks/versioning?lang=python#stripe-sdk-language-version-support-policy
#### Extended Support
#### Python 2.7 deprecation
[The Python Software Foundation (PSF)](https://www.python.org/psf-landing/) community [announced the end of support of Python 2](https://www.python.org/doc/sunset-python-2/) on 01 January 2020.
Starting with version 6.0.0 Stripe SDK Python packages will no longer support Python 2.7. To continue to get new features and security updates, please make sure to update your Python runtime to Python 3.6+.
The last version of the Stripe SDK that supported Python 2.7 was **5.5.0**.
## Usage
The library needs to be configured with your account's secret key which is
available in your [Stripe Dashboard][api-keys]. Set `stripe.api_key` to its
value:
```python
from stripe import StripeClient
client = StripeClient("sk_test_...")
# list customers
customers = client.v1.customers.list()
# print the first customer's email
print(customers.data[0].email)
# retrieve specific Customer
customer = client.v1.customers.retrieve("cus_123456789")
# print that customer's email
print(customer.email)
```
### StripeClient vs legacy pattern
We introduced the `StripeClient` class in v8 of the Python SDK. The legacy pattern used prior to that version is still available to use but will be marked as deprecated soon. Review the [migration guide to use StripeClient](<https://github.com/stripe/stripe-python/wiki/Migration-guide-for-v8-(StripeClient)>) to move from the legacy pattern.
Once the legacy pattern is deprecated, new API endpoints will only be accessible in the StripeClient. While there are no current plans to remove the legacy pattern for existing API endpoints, this may change in the future.
### Handling exceptions
Unsuccessful requests raise exceptions. The class of the exception will reflect
the sort of error that occurred. Please see the [Api
Reference](https://stripe.com/docs/api/errors/handling) for a description of
the error classes you should handle, and for information on how to inspect
these errors.
### Per-request Configuration
Configure individual requests with the `options` argument. For example, you can make
requests with a specific [Stripe Version](https://stripe.com/docs/api#versioning)
or as a [connected account](https://stripe.com/docs/connect/authentication#authentication-via-the-stripe-account-header):
```python
from stripe import StripeClient
client = StripeClient("sk_test_...")
# list customers
client.v1.customers.list(
options={
"api_key": "sk_test_...",
"stripe_account": "acct_...",
"stripe_version": "2019-02-19",
}
)
# retrieve single customer
client.v1.customers.retrieve(
"cus_123456789",
options={
"api_key": "sk_test_...",
"stripe_account": "acct_...",
"stripe_version": "2019-02-19",
}
)
```
### Configuring an HTTP Client
You can configure your `StripeClient` to use `urlfetch`, `requests`, `pycurl`, or
`urllib` with the `http_client` option:
```python
client = StripeClient("sk_test_...", http_client=stripe.UrlFetchClient())
client = StripeClient("sk_test_...", http_client=stripe.RequestsClient())
client = StripeClient("sk_test_...", http_client=stripe.PycurlClient())
client = StripeClient("sk_test_...", http_client=stripe.UrllibClient())
```
Without a configured client, by default the library will attempt to load
libraries in the order above (i.e. `urlfetch` is preferred with `urllib2` used
as a last resort). We usually recommend that people use `requests`.
### Configuring a Proxy
A proxy can be configured with the `proxy` client option:
```python
client = StripeClient("sk_test_...", proxy="https://user:pass@example.com:1234")
```
### Configuring Automatic Retries
You can enable automatic retries on requests that fail due to a transient
problem by configuring the maximum number of retries:
```python
client = StripeClient("sk_test_...", max_network_retries=2)
```
Various errors can trigger a retry, like a connection error or a timeout, and
also certain API responses like HTTP status `409 Conflict`.
[Idempotency keys][idempotency-keys] are automatically generated and added to
requests, when not given, to guarantee that retries are safe.
### Logging
The library can be configured to emit logging that will give you better insight
into what it's doing. The `info` logging level is usually most appropriate for
production use, but `debug` is also available for more verbosity.
There are a few options for enabling it:
1. Set the environment variable `STRIPE_LOG` to the value `debug` or `info`
```sh
$ export STRIPE_LOG=debug
```
2. Set `stripe.log`:
```python
import stripe
stripe.log = 'debug'
```
3. Enable it through Python's logging module:
```python
import logging
logging.basicConfig()
logging.getLogger('stripe').setLevel(logging.DEBUG)
```
### Accessing response code and headers
You can access the HTTP response code and headers using the `last_response` property of the returned resource.
```python
customer = client.v1.customers.retrieve(
"cus_123456789"
)
print(customer.last_response.code)
print(customer.last_response.headers)
```
### Writing a Plugin
If you're writing a plugin that uses the library, we'd appreciate it if you
identified using `stripe.set_app_info()`:
```py
stripe.set_app_info("MyAwesomePlugin", version="1.2.34", url="https://myawesomeplugin.info")
```
This information is passed along when the library makes calls to the Stripe
API.
### Telemetry
By default, the library sends telemetry to Stripe regarding request latency and feature usage. These
numbers help Stripe improve the overall latency of its API for all users, and
improve popular features.
You can disable this behavior if you prefer:
```python
stripe.enable_telemetry = False
```
## Types
In [v7.1.0](https://github.com/stripe/stripe-python/releases/tag/v7.1.0) and
newer, the
library includes type annotations. See [the wiki](https://github.com/stripe/stripe-python/wiki/Inline-type-annotations)
for a detailed guide.
Please note that some annotations use features that were only fairly recently accepted,
such as [`Unpack[TypedDict]`](https://peps.python.org/pep-0692/#specification) that was
[accepted](https://discuss.python.org/t/pep-692-using-typeddict-for-more-precise-kwargs-typing/17314/81)
in January 2023. We have tested that these types are recognized properly by [Pyright](https://github.com/microsoft/pyright).
Support for `Unpack` in MyPy is still experimental, but appears to degrade gracefully.
Please [report an issue](https://github.com/stripe/stripe-python/issues/new/choose) if there
is anything we can do to improve the types for your type checker of choice.
### Types and the Versioning Policy
We release type changes in minor releases. While stripe-python follows semantic
versioning, our semantic versions describe the _runtime behavior_ of the
library alone. Our _type annotations are not reflected in the semantic
version_. That is, upgrading to a new minor version of stripe-python might
result in your type checker producing a type error that it didn't before. You
can use a `~=x.x` or `x.x.*` [version specifier](https://peps.python.org/pep-0440/#examples)
in your `requirements.txt` to constrain `pip` to a certain minor range of `stripe-python`.
### Types and API Versions
The types describe the [Stripe API version](https://stripe.com/docs/api/versioning)
that was the latest at the time of release. This is the version that your library
sends by default. If you are overriding `stripe.api_version` / `stripe_version` on the `StripeClient`, or using a
[webhook endpoint](https://stripe.com/docs/webhooks#api-versions) tied to an older version,
be aware that the data you see at runtime may not match the types.
### Public Preview SDKs
Stripe has features in the [public preview phase](https://docs.stripe.com/release-phases) that can be accessed via versions of this package that have the `bX` suffix like `12.2.0b2`.
We would love for you to try these as we incrementally release new features and improve them based on your feedback.
To install, pick the latest version with the `bX` suffix by reviewing the [releases page](https://github.com/stripe/stripe-python/releases/) and then use it in the `pip install` command:
```
pip install stripe==<replace-with-the-version-of-your-choice>
```
> **Note**
> There can be breaking changes between two versions of the public preview SDKs without a bump in the major version. Therefore we recommend pinning the package version to a specific version in your [pyproject.toml](https://packaging.python.org/en/latest/guides/writing-pyproject-toml/#dependencies-and-requirements) or [requirements file](https://pip.pypa.io/en/stable/user_guide/#requirements-files). This way you can install the same version each time without breaking changes unless you are intentionally looking for the latest public preview SDK.
Some preview features require a name and version to be set in the `Stripe-Version` header like `feature_beta=v3`. If your preview feature has this requirement, use the `stripe.add_beta_version` function (available only in the public preview SDKs):
```python
stripe.add_beta_version("feature_beta", "v3")
```
### Private Preview SDKs
Stripe has features in the [private preview phase](https://docs.stripe.com/release-phases) that can be accessed via versions of this package that have the `aX` suffix like `12.2.0a2`. These are invite-only features. Once invited, you can install the private preview SDKs by following the same instructions as for the [public preview SDKs](https://github.com/stripe/stripe-python?tab=readme-ov-file#public-preview-sdks) above and replacing the suffix `b` with `a` in package versions.
### Custom requests
If you would like to send a request to an undocumented API (for example you are in a private beta), or if you prefer to bypass the method definitions in the library and specify your request details directly, you can use the `raw_request` method on `StripeClient`.
```python
client = StripeClient("sk_test_...")
response = client.raw_request(
"post", "/v1/beta_endpoint", param=123, stripe_version="2022-11-15; feature_beta=v3"
)
# (Optional) response is a StripeResponse. You can use `client.deserialize` to get a StripeObject.
deserialized_resp = client.deserialize(response, api_mode='V1')
```
### Async
Asynchronous versions of request-making methods are available by suffixing the method name
with `_async`.
```python
# With StripeClient
client = StripeClient("sk_test_...")
customer = await client.v1.customers.retrieve_async("cus_xyz")
# With global client
stripe.api_key = "sk_test_..."
customer = await stripe.Customer.retrieve_async("cus_xyz")
# .auto_paging_iter() implements both AsyncIterable and Iterable
async for c in await stripe.Customer.list_async().auto_paging_iter():
...
```
There is no `.save_async` as `.save` is [deprecated since stripe-python v5](https://github.com/stripe/stripe-python/wiki/Migration-guide-for-v5#deprecated). Please migrate to `.modify_async`.
The default HTTP client uses `requests` for making synchronous requests but
`httpx` for making async requests. If you're migrating to async, we recommend
you to explicitly initialize your own http client and pass it to StripeClient
or set it as the global default.
If you don't already have a dependency on an async-compatible HTTP library, `pip install stripe[async]` will install one for you (new in `v13.0.1`).
```python
# By default, an explicitly initialized HTTPXClient will raise an exception if you
# attempt to call a sync method. If you intend to only use async, this is useful to
# make sure you don't unintentionally make a synchronous request.
my_http_client = stripe.HTTPXClient()
# If you want to use httpx to make sync requests, you can disable this
# behavior.
my_http_client = stripe.HTTPXClient(allow_sync_methods=True)
# aiohttp is also available (does not support sync requests)
my_http_client = stripe.AIOHTTPClient()
# With StripeClient
client = StripeClient("sk_test_...", http_client=my_http_client)
# With the global client
stripe.default_http_client = my_http_client
```
You can also subclass `stripe.HTTPClient` and provide your own instance.
## Support
New features and bug fixes are released on the latest major version of the Stripe Python library. If you are on an older major version, we recommend that you upgrade to the latest in order to use the new features and bug fixes including those for security vulnerabilities. Older major versions of the package will continue to be available for use, but will not be receiving any updates.
## Development
[Contribution guidelines for this project](CONTRIBUTING.md)
The test suite depends on [stripe-mock], so make sure to fetch and run it from a
background terminal ([stripe-mock's README][stripe-mock] also contains
instructions for installing via Homebrew and other methods):
```sh
go install github.com/stripe/stripe-mock@latest
stripe-mock
```
We use [just](https://github.com/casey/just) for conveniently running development tasks. You can use them directly, or copy the commands out of the `justfile`. To our help docs, run `just`. By default, all commands will use an virtualenv created by your default python version (whatever comes out of `python --version`). We recommend using [mise](https://mise.jdx.dev/lang/python.html) or [pyenv](https://github.com/pyenv/pyenv) to control that version.
Run the following command to set up the development virtualenv:
```sh
just venv
# or: python -m venv venv && venv/bin/python -I -m pip install -e .
```
Run all tests:
```sh
just test
# or: venv/bin/pytest
```
Run all tests in a single file:
```sh
just test tests/api_resources/abstract/test_updateable_api_resource.py
# or: venv/bin/pytest tests/api_resources/abstract/test_updateable_api_resource.py
```
Run a single test suite:
```sh
just test tests/api_resources/abstract/test_updateable_api_resource.py::TestUpdateableAPIResource
# or: venv/bin/pytest tests/api_resources/abstract/test_updateable_api_resource.py::TestUpdateableAPIResource
```
Run a single test:
```sh
just test tests/api_resources/abstract/test_updateable_api_resource.py::TestUpdateableAPIResource::test_save
# or: venv/bin/pytest tests/api_resources/abstract/test_updateable_api_resource.py::TestUpdateableAPIResource::test_save
```
Run the linter with:
```sh
just lint
# or: venv/bin/python -m flake8 --show-source stripe tests
```
The library uses [Ruff][ruff] for code formatting. Code must be formatted
with Black before PRs are submitted, otherwise CI will fail. Run the formatter
with:
```sh
just format
# or: venv/bin/ruff format . --quiet
```
