* [python] fix#19255 add async httpx support
* update docs
* 1. "async" parameter for templates
2. hand written tests for python-httpx
3. CI workflow updated
* fix mypy
* Validate pyproject.toml of echo client python sample
* Use PEP-508 compatible version constraint for `requires-python` key
* Update samples
* Move job to petstore workflow
* Update generated sample
* Use equals or greater than operator instead of greater than
* Update samples
* Drop support for python 3.8 and add support for 3.13 in python generator templates
* Update docs
* Test samples without python 3.8 and with 3.13
* Generate samples
Python 3.12 has been released in October 2023, it should be tested in
the CI.
Python 3.7 is not maintained anymore, removing it from the minimum
required version in `pyproject.toml` files.
* python: adjust basic typing information
This is an initial pass to fix and adjust the typing information for the
generated client. This is enough to have mypy runnning without complains
on all the (modern) generated clients (Pydantic v1 code is not checked
for instance)
mypy is also now run directly in the CI, so further changes will also be
checked and thus, will need to be compliant with good typing
information.
Note that this doesn't *fully* type all the code: mypy is not run in
"strict" mode and there are still many functions/methods/attributes
which are still not fully typed, but it's a first good step in that
direction.
* ApiResponse's raw_data can't be None
* Fix indentation
* Revert test changes
* run mypy on tests/ directory
* don't forcefully convert the client response headers to dict
* override petstore ApiResponse model
* adjust type of 'any/one_of_schemas' fields
