python3-mypy-extensions binary package in Ubuntu Noble arm64

 Add type annotations to your Python programs, and use mypy to type check them.
 Mypy is essentially a Python linter on steroids, and it can catch many
 programming errors by analyzing your program, without actually having to run
 it. Mypy has a powerful type system with features such as type inference,
 gradual typing, generics and union types.
 .
 The "mypy_extensions" module defines experimental extensions to the
 standard "typing" module that are supported by the mypy typechecker.
 .
 This package provides the modules for Python 3.
