Python - ctrl L does not work

问题

Attempting to use Ctrl+L for clearing Power Sheel in Python 2.7.8 I get no response.

Is there any problem in Windows 10?

回答1:

Ctrl+L only works on Linux/OS X terminals. It does not work on Windows. To clear the screen on Windows you could do the following:

import os
os.system('cls')

回答2:

To extend Kredns answer to Linux/OS X terminals as well:

import os
os.system('clear')

回答3:

I like Kredns's answer, however, you have to type all of that every time. I made a module/function. Okay, I am using Python 3.7.3, but similar answer for Python 2.

def cls():
    import os
    os.system('cls')
    return 

Save this as a script and import cls or whatever you want to call it. Import that (e.g. on python start up). So if you're in the correct directory:

from cls import cls

Then call it with cls() whenever you want to clear the screen.

cls()

IdleX extension of IDLE has the functionality you are looking for. Try installing from here http://idlex.sourceforge.net/ OR https://pypi.org/project/idlex/

pressing CTRL-L, works in the intutive way (clear the console and take you to the top with a prompt, and doesn't clear the variables and definitions you have defined yet)
