If You Mean to Clear the Screen in the Console:

If you’re looking to clear the screen in a console application, you can use platform-specific solutions. Here’s an example using the os module, which works on many systems:

import os

# For Windows
if os.name == 'nt':
    os.system('cls')
# For Unix/Linux/MacOS
else:
    os.system('clear')

Note: the above code for clearing the console screen is platform-dependent.
