How to clear the interpreter console?


Question

Like most Python developers, I typically keep a console window open with the Python interpreter running to test commands, dir() stuff, help() stuff, etc.

Like any console, after a while the visible backlog of past commands and prints gets to be cluttered, and sometimes confusing when re-running the same command several times. I'm wondering if, and how, to clear the Python interpreter console.

I've heard about doing a system call and either calling cls on Windows or clear on Linux, but I was hoping there was something I could command the interpreter itself to do.

Note: I'm running on Windows, so Ctrl+L doesn't work.

Accepted Answer

As you mentioned, you can do a system call:

For Windows

>>> import os
>>> clear = lambda: os.system('cls')
>>> clear()

For Linux the lambda becomes

>>> clear = lambda: os.system('clear')

here something handy that is a little more cross-platform

import os

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

# now, to clear the screen
cls()
