How to clear screen

Question

I'm writing a program to simulate a page to create an account and log in.
(check out on: https://code.sololearn.com/cfqgqjMeE1sV/#py)
I've searched for a function/statement to clear the screen everytime I change from "create account page" to "log in page", but I didn't find anything that worked.
I tried:
def clear():
os.system('cls')
but I failed.
So, as a temporary solution, I printed 100 new lines to have the same effect.
I wonder, is there any other way to do this? Thanks in advance.
PS: check out my other codes if you like ;)

Answer 1

@David Najafi I tried this:
>>> import os
>>> clear = lambda: os.system('cls')
>>> clear()
but a cmd prompt poped up and vanished instantly, but nothing changed on my program
I also tried on linux, replacing 'cls' by 'clear' but didn't work either

Answer 2

@David Najafi I tried on IDLE and pycharm but didn't worked

Answer 3

@David Najafi I work with Windows and I used import. Still, didn't work

Answer 4

The playground of SoloLearn does not support some functions. Like OS functions. Or httpservice functions, for php and other languages.

And c++ in SOLOLEARN does not support some header files like Windows.h

Answer 5

For Windows DON'T FORGET THE IMPORT

import os
os.system("cls")

For OS X, you can use subprocess module and call 'cls' from shell:

import subprocess as sp
sp.call('cls',shell=True)
To prevent '0' from showing on top of the window, replace the 2nd line with:

tmp = sp.call('cls',shell=True)
For linux, you must replace cls command with clear

tmp = sp.call('clear',shell=True)

Answer 6

Call it like this

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

Answer 7

try assigning os.system to a variable so it doesn't return 0

Answer 8

If you are writing your code on Android,
which is based on Linux, then use the
following -
import os , then
os.system("clear")

Answer 9

import os
os.system('cls')
