When programming in Python using the interactive shell, you can see the output after running every script. This can make the screen a bit clumsy and you might have problems locating a particular output. In that case, you might want to clear the screen.
You might want to clear the screen while executing a python script. Unfortunately, there’s no built-in keyword or function/method to do so. So, you have to do it on your own.
How to clear the shell screen in Python?
We will look here following ways to clear the Python output screen in this article:
- Using ANSI Escape
- Using the Subprocess Module
- Using the OS Module
- Using Click Module
- Custom Program to Clear Screen
- Using Clear-Screen Class
1) Using ANSI Escape
You can use ANSI escape sequences. But these are not portable and may not produce the output you are looking for.
The most common ways to clear an interactive shell screen on Windows and Linux platforms are given below –
For Windows terminals:
For Linux / OS X platforms:
If you want to clear a screen on other programming environments other than Python, such as Bash, MySQL or MATLAB, just press CTRL + L.
2) Using the Subprocess Module
You can use the subprocess module in Python to clear the output screen.
import subprocess as sp sp.call('cls',shell=True)
The second line of the code must be replaced with tmp = sp.call(‘cls’,shell=True), to prevent 0 from popping up at the top of the output screen.
import subprocess as sp sp.call('clear',shell=True)
Replace the second line of the code with tmp = sp.call(‘clear’,shell=True) for the reason mentioned earlier.
3) Using the OS Module
Use the import statement to load the os library. Then use the system method and pass ‘cls’ as the parameter to clear the output screen.
import os os.system('cls')
Linux/ OS X:
import os os.system('clear')
4) Using Click Module
The click module works on Windows, Linux and OS X platforms.
import click click.clear()
5) Custom Program to Clear Screen
You can write a Python program to clear the screen –
# The code works on all platforms such as Windows, Linux and OS-X import platform # For obtaining the operating system information import os # Import the os module to clear screen def clr_scr(): #Python program to clear screen #Get command to execute if(platform.system().lower()=="windows"): cmd='cls' else: cmd='clear' # Run command os.system(cmd) # Call function to clear screen clr_scr()
6) Using Clear-Screen Class
from clear_screen import clear # Python program to clear screen # Using clear Module # Import clear_screen Class from clear Module from clear_screen import clear # execute function clear() clear()
As discussed above, there are multiple ways through which you can clear the screen in Python. It also depends on the module you have installed.
If you are running Python scripts on multiple platforms, then you can use the clear command, click module or can just create your own program to clear the interactive shell screen. Make sure you have properly loaded modules using the import statement before using them.
