Ctypes Module

ctypes is a foreign function interface module for Python, which allows you to load in dynamic libraries and call C functions.

This is not technically extending Python, but it serves one of the primary reasons for extending Python: to interface with external C code.

import ctypes

# unter Windows:

# libc = ctypes.CDLL("MSVCRT")

# unter Linux:

libc = ctypes.CDLL("libc.so.6")

libc.printf(b"Hallo Welt\n")

#libc.printf("Hallo Welt\n") Python2

x = libc.rand();

print(x)

x = libc.putchar(48);

Muss groß geschrieben werden und ohne .dll
