def clear() in PyCharm

Hi there,

Could anybody clarify why def clear() doesn't work in PyCharm and how it can be solved in PyCharm?

Many thanks in advance

Hi Dmitriy, I am using PyCharm on a Mac

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

This is my code for the clear screen function, exactly like Kenneth shows in the video and the clear() function worked perfectly for me.

It looks like you have a space in front of " nt". try 'nt' os.system('cls' if os.name == ' nt' else 'clear') I hope this worked! It hard to notice spaces!

I found the answer after a google search:

On PyCharm, click "Run", "Edit Configurations", tick "Emulate terminal in output console".

The answer found on overstack.com:

In the current version of PyCharm on Linux it is possible to use os.system("clear"). You have to edit the 'Run/Debug Configuration' and tick the box 'Emulate terminal in output console'. I assume it works on Windows with os.system("cls") as well.
