We’ve 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:
python3 -m pip install -U mypy
You can read the full documentation for this release on Read the Docs.
Support Python 3.12 Syntax for Generics (PEP 695)
Mypy now supports the new type parameter syntax introduced in Python 3.12 (PEP 695).
This feature is still experimental and must be enabled with the --enable-incomplete-feature=NewGenericSyntax flag, or with enable_incomplete_feature = NewGenericSyntax in the mypy configuration file.
We plan to enable this by default in the next mypy feature release.
This example demonstrates the new syntax:
# Generic function
def f[T](https://github.com/python/mypy/blob/master/x: T) -> T: ...
reveal_type(f(1)) # Revealed type is 'int'
Generic class
class C[T]:
def init(self, x: T) -> None:
self.x = x
c = C('a')
reveal_type(c.x) # Revealed type is 'str'
Type alias
type A[T] = C[list[T]]
This feature was contributed by Jukka Lehtosalo.
Support for functools.partial
Mypy now type checks uses of functools.partial. Previously mypy would accept arbitrary arguments.
