| - :cython:ref:`cpdef <cpdef>` function combines both ``cdef`` and ``def``. | ||
| - Cython will generate a ``cdef`` function for C types and a ``def`` function for Python types. | ||
| - In terms of performance, ``cpdef`` functions may be *as fast as* those using ``cdef`` and might be as slow as ``def`` declared functions. | ||

@ashwinvis since this example, when i switch between "pure python" and "cython", it jumps a little bit which is disturbing

@ashwinvis do you have to mention data type like Py_ssize_t somewhere?
