How to clear cmd/terminal while running a python script

问题

I keep seeing ways to clear the shell while running a script, however is there a way to clear the screen while running a script in the CMD? My current method works like this:

clear.py

import title
def clear():
    print('\n' * 25)
    title.title()

game.py

from engine import clear
clear.clear()
print(Fore.CYAN + Style.BRIGHT + "--------------------------------")

However this method isn't really reliable as some cmd sizes are different on all computers, nor have I tried it on OSx.

回答1:

Here's another way, that handles Windows cases as well as Unix-like systems (Linux, OSX, etc.):

import os
os.system('cls' if os.name == 'nt' else 'clear')

The clear command works in all Unix-like systems (ie, OSX, Linux, etc.). The Windows equivalent is cls.

Your best bet is probably to use the colorama module to enable ANSI escape sequences in the Windows terminal, and then use the ANSI sequence to clear the screen:

import colorama
colorama.init()
print("\033[2J\033[1;1f")

This should work on all common platforms.
