How to clear screen/terminal in python

Question

I have tried the commands to clear the terminal, for both Windows and Linux, but they are not working(I use a windows computer). This is my program:

print(1)

import os          # line 1
os.system('cls')   # line 2

print(1)

I have also tried using this:

import os
os.system('ls')

This code is also not working:

import os
os.system('clear')

What else can I try to clear the python output terminal?
