Collection of library stubs for Python, with static types
Improve documentation for decisions around certain `list`, `dict`, `Mapping`, and `Sequence` methods
[`list.index`](https://github.com/python/typeshed/blob/35064a7f759facd7c3787ab6095964008f97d873/stdlib/builtins.pyi#L797) and [`list.count`](https://github.com/python/typeshed/blob/35064a7f759facd7c3787ab6095964008f97d873/stdlib/builtins.pyi#L798) currently only accepts values of the element type and [`Sequence.index`](https://github.com/python/typeshed/blob/35064a7f759facd7c3787ab6095964008f97d873/stdlib/typing.pyi#L328) and [`Sequence.count`](https://github.com/python/typeshed/blob/35064a7f759facd7c3787ab6095964008f97d873/stdlib/typing.pyi#L329) use `Any` for the type of the argument. In my opinion all of these functions...
`mypy_test.py` has two command-line arguments that I find somewhat useless: `filter` and `exclude`. (It looks like they've stayed more-or-less the same since the script's inception 7 years ago.) I'd like...
According to https://github.com/psf/requests/blob/2d5517682b3b38547634d153cea43d48fbc8cdb5/requests/models.py#L170 It should be possible to provide `files={"fieldname": ("filename", [bytes-object])}`, but since the last update of mypy this fails with ``` packet_analyser/daemon/uploader.py:78: error: Argument "files" to "post" has...
In https://github.com/python/typeshed/pull/4989 the return types of the pipeline methods were changed so that they would all return pipeline instances, but that's not always correct. If the pipeline is watching keys...
Example: `stubs/paramiko/paramiko/kex_ecdh_nist.pyi` contains imports from `cryptography`, but pyright can't find `cryptograpy`, probably because it's "hidden" in `stubs/cryptography`. Cc @erictraut and @jakebailey: Do you have any ideas how we could fix...
At the moment, whenever there is change to typeshed, we test all stdlib and third-party packages in the same testing environment, using the `--custom-typeshed-dir` so that all packages can see...
Here's a minimal reproducer: ```python from __future__ import annotations from functools import partialmethod class A: def my_add(self, other: A, reverse: bool) -> A: return self __add__ = partialmethod(my_add, reverse=False) a...
I got a new regression from the latest release on a real project: https://github.com/wemake-services/wemake-python-styleguide/blob/master/wemake_python_styleguide/logic/arguments/function_args.py#L125-L126 Error: ``` wemake_python_styleguide/logic/arguments/function_args.py:126: error: Argument 1 to "get" of "Mapping" has incompatible type "Optional[Any]"; expected "str"...
Our `CONTRIBUTING.md` guide says that [all names in `__all__`](https://github.com/python/typeshed/blob/master/CONTRIBUTING.md#what-to-include) should be included. But, should `__all__` itself be defined? I've seen that some modules do have `__all__` inside. Some - don't....
Many of the core stdlib stubs, including `builtins.pyi` import symbols from `typing_extensions`. The `typing_extensions.pyi` stub is now part of the stdlib stubs, but for a short period of time after...
