\nNext release
\nMypy 1.11
\nWe\u2019ve just uploaded mypy 1.11 to the Python Package Index (PyPI). Mypy is a static type checker for Python. This release includes new features, performance improvements and bug fixes. You can install it as follows:
\n\npython3 -m pip install -U mypy\nYou can read the full documentation for this release on Read the Docs.
\nSupport Python 3.12 Syntax for Generics (PEP 695)
\nMypy now supports the new type parameter syntax introduced in Python 3.12 (PEP 695).\nThis feature is still experimental and must be enabled with the
\n--enable-incomplete-feature=NewGenericSyntaxflag, or withenable_incomplete_feature = NewGenericSyntaxin the mypy configuration file.\nWe plan to enable this by default in the next mypy feature release.This example demonstrates the new syntax:
\n\n# Generic function\ndef f[T](https://github.com/python/mypy/blob/master/x: T) -> T: ...\nreveal_type(f(1)) # Revealed type is 'int'
\nGeneric class
\nclass C[T]:\ndef init(self, x: T) -> None:\nself.x = x
\nc = C('a')\nreveal_type(c.x) # Revealed type is 'str'
\nType alias
\ntype A[T] = C[list[T]]\n
This feature was contributed by Jukka Lehtosalo.
\nSupport for
\nfunctools.partialMypy now type checks uses of
\nfunctools.partial. Previously mypy would accept arbitrary arguments.This example will now produce an error:
\n\nfrom functools import partial\n</tr></table> \n
