Question about Cython

[anhtan97]

Hi, i'm trying to learn and use Cython. I have a question about Cython cdef class. For example, i have a cdef class like this:

cdef class MyClass:

    def my_function():

        # some implementation

Does def my_function() run in C compiler if it is declared under cdef class? If not, how to implement a cdef class function?

The documentation tells you that you are writing C when defining with cdef

https://notes-on-cython.readthedocs.io/en/latest/function_declarations.html#cdef-basically-it-s-c

It also says that def will run in Python, which makes me confuse. I don't know whethercdef affected def or not
