Cython typing
WebThe Cython programming language enriches Python by C-like static typing, the ability to directly call C functions, and several other features. This allows to reach C-level performance while still using a Python-like syntax. WebCython is much more focused on performance than mypy. Mypy is only about static type checking, and increasing performance is not a direct goal. The mypy syntax is arguably simpler and more “Pythonic” (no cdef/cpdef, etc.) for statically typed code. The mypy syntax is compatible with Python.
