Generation Details

In python a preffered way to check types equality is using is operator or using a issubclass().

>>> class T(str): ...
>>> T == str
False
>>> T is str
False
>>> str == str
True
>>> str is str
True
>>> issubclass(T, str)
True
>>> issubclass(str, str)
True
>>> 

Steps to reproduce

git clone git@github.com:OpenAPITools/openapi-generator.git
cd openapi-generator/samples/client/echo_api/python
docker run -v .:/io --rm ghcr.io/astral-sh/ruff check --fix

actual output:

warning: Invalid rule code provided to `# noqa` at setup.py:16: H301
E721 Use `is` and `is not` for type comparisons, or `isinstance()` for isinstance checks

change == operator with issubclass() calls (it is already used for Enum type)
