What does C_Int * Len(Pyarr) do in Python?

This is an explanation of the accepted answer. ctypes.c_int * len (pyarr) creates an array (sequence) of type c_int of length 4 ( python3, python 2 ). Since c_int is an object whose constructor takes one argument, (ctypes.c_int * len (pyarr) (*pyarr) does a one shot init of each c_int instance from pyarr.
