'clear' is not recognized as an internal or external command

Hi Michael,

I'm just starting your Python for Entrepreneurs course and am enjoying it so far.

I just finished the Python language refresher game and although my code runs, it contains this message about the word 'clear'. (see below)

I tried copying your code from github into my file and the message still displays, so I don't think it's a bug in my code, but perhaps some system setting that needs changing. I'm on Windows 7 and using PyCharm.

Couldn't find the exact fix on Stackoverflow so I thought I'd ask you how to get rid of it, it's more annoying than anything. Thank you. -Ian

Hi,

The error is because I didn't check whether you're on Windows or a *nix based system. If you change clear to cls it will work.

The most recent check-in fixes the issue:

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

Thanks for letting me know about this error.
