Question

I recently came across a python code this is given below is doesn't not give any output and it is a python 2.5 command but I am using python 3.9.1
The code is :

from ctypes import *

msvcrt = cdll.msvcrt

message_string = b"Hello world!\n"
msvcrt.printf(b"Testing: %s", message_string)

desired output : Testing: Hello world!

Python2 and Python3 are actually two different lenguages (the first is not even supported any more)

Chances are (I'm 100% sure) that the library has changed, so check out the newest documentation and update (or should I say translate) that code
