The sort of thing that you are looking for is to be found in the curses module.

i.e.

import curses  # Get the module
stdscr = curses.initscr()  # initialise it
stdscr.clear()  # Clear the screen

Important Note

The important thing to remember is before any exit, you need to reset the terminal to a normal mode, this can be done with the following lines:

curses.nocbreak()
stdscr.keypad(0)
curses.echo()
curses.endwin()

If you don’t you will get all sort of strange behaviour. To ensure that this is always done I would suggest using the atexit module, something like:

import atexit

@atexit.register
def goodbye():
    """ Reset terminal from curses mode on exit """
    curses.nocbreak()
    if stdscr:
        stdscr.keypad(0)
    curses.echo()
    curses.endwin()

Will probably do nicely.

import curses
stdscr = curses.initscr()
stdscr.clear()

import os

os.system('cls')  # For Windows
os.system('clear')  # For Linux/OS X

Subprocess allows you to call “cls” for Shell.

import subprocess
cls = subprocess.call('cls',shell=True)

That’s as simple as I can make it. Hope it works for you!

An easier way to clear a screen while in python is to use Ctrl + L though it works for the shell as well as other programs.

If you are using linux terminal to access python, then cntrl+l is the best solution to clear screen

What about the shortcut CTRL+L?

It works for all shells e.g. Python, Bash, MySQL, MATLAB, etc.

1. you can Use Window Or Linux Os

   import os
   os.system('cls')
   os.system('clear')
   

2. you can use subprocess module

   import subprocess as sp
   x=sp.call('cls',shell=True)
   

os.system('cls') works fine when I open them. It opens in cmd style.

using windows 10 and pyhton3.5 i have tested many codes and nothing helped me more than this:

First define a simple function, this funtion will print 50 newlines;(the number 50 will depend on how many lines you can see on your screen, so you can change this number)

def cls(): print ("n" * 50)

then just call it as many times as you want or need

cls()

Here are some options that you can use on Windows

First option:

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

>>> cls()

Second option:

cls = lambda: print('n' * 100)

>>> cls()

Third option if you are in Python REPL window:

Ctrl+L

This function works in any OS (Unix, Linux, macOS, and Windows)
Python 2 and Python 3

import platform    # For getting the operating system name
import subprocess  # For executing a shell command

def clear_screen():
    """
    Clears the terminal screen.
    """

    # Clear command as function of OS
    command = "cls" if platform.system().lower()=="windows" else "clear"

    # Action
    return subprocess.call(command) == 0

In windows the command is cls, in unix-like systems the command is clear.
platform.system() returns the platform name. Ex. 'Darwin' for macOS.
subprocess.call() performs a system call. Ex. subprocess.call(['ls','-l'])

In addition to being an all-around great CLI library, click also provides a platform-agnostic clear() function:

import click
click.clear()

Command+K works fine in OSX to clear screen.

Shift+Command+K to clear only the scrollback buffer.

I am using a class that just uses one of the above methods behind the scenes… I noticed it works on Windows and Linux… I like using it though because it’s easier to type clear() instead of system(‘clear’) or os.system(‘clear’)

pip3 install clear-screen

from clear_screen import clear

and then when you want to clear the shell:

clear()

Here’s how to make your very own cls or clear command that will work without explicitly calling any function!

We’ll take advantage of the fact that the python console calls repr() to display objects on screen. This is especially useful if you have your own customized python shell (with the -i option for example) and you have a pre-loading script for it. This is what you need:

import os
class ScreenCleaner:
    def __repr__(self):
        os.system('cls')  # This actually clears the screen
        return ''  # Because that's what repr() likes

cls = ScreenCleaner()

Use clear instead of cls if you’re on linux (in both the os command and the variable name)!

Now if you just write cls or clear in the console – it will clear it! Not even cls() or clear() – just the raw variable. This is because python will call repr(cls) to print it out, which will in turn trigger our __repr__ function.

Let’s test it out:

>>> df;sag
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
NameError: name 'df' is not defined
>>> sglknas
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
NameError: name 'sglknas' is not defined
>>> lksnldn
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
NameError: name 'lksnldn' is not defined
>>> cls

And the screen is clear!

To clarify – the code above needs to either be imported in the console like this

from somefile import cls

Or pre load directly with something like:

python -i my_pre_loaded_classes.py

Rather than importing all of curses or shelling out just to get one control character, you can simply use (on Linux/macOS):

print(chr(27) + "[2J")

(Source: Clear terminal in Python)

That’s the best way:

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

For the Python IDLE 3.8.1 you can restart the Shell

CTRL + F6

On the menu Click on the Shell menu.
Then click on the Restart Shell option.
