PEP-484 type annotations ¶ Python type hints can be used to declare argument types, as shown in the following example: import cython def func(foo: dict, bar: cython.int) -> tuple: foo["hello world"] = 3 + bar return foo, 5 WebImporting Cython Functions The function get_cython_function_address obtains the address of a C function in a Cython extension module. The address can be used to access the C function via a ctypes.CFUNCTYPE () callback, thus allowing use of the C function inside a Numba jitted function. For example, suppose that you have the file foo.pyx:
