Clear terminal in Python

Diversify your toolbox

Step beyond the straightforward os.system approach and explore other methods within Python's standard library:

Control terminal using escape sequences

Try using a raw escape sequence which functions without shell commands:

print("\033[H\033[J", end="")


Here, \033[H moves your cursor to the origin (i.e., top-left corner; programmers' "home sweet home"). \033[J then clears everything from this point onwards, effectively giving you a fresh screen.

Subprocess: the power tool

Command more control over the execution and output handling by using the subprocess module:

import subprocess

subprocess.run('cls' if os.name == 'nt' else 'clear', shell=True)


Note: subprocess.run is like the Swiss Army knife of shell commands, handling them with grace and precision.

Keeping your buffer clean

On Linux and macOS, clearing the visible terminal might seem satisfactory, but the scrollback buffer holds residue. To clear this, run:

print("\033c\033[3J", end="")


Here \033c reset is like the memory of an old fish—it forgets everything about the terminal's previous state. Meanwhile, \033[3J is like a vacuum cleaner—it clears away all the dusty old data from the buffer.

Terminal management and cursor control

While a clean space is a knack of productive development, managing your cursor and buffer can further streamline your terminal experience:

Clear without adding newline

Purge the screen without introducing a newline. Just set end as an empty string in the print function:

print("\033[H\033[J", end="")


This is like cleaning your room without accidentally knocking over your JavaScript mug.

Clearing screen with subprocess

You can clean your terminal using subprocess with the printf command from the shell:

import subprocess

subprocess.run("printf '\033c'", shell=True)


Isn't cleanliness close to godliness even at the terminal level?!

Cursor styling

Using \033[0 q sequence, you can change your terminal cursor to blink, say into a steady block:

print("\033[2 q")  # The birth of a cool blinking block cursor.


By understanding and utilizing such escape codes, you not only keep your terminal clean but also make it an exciting place to work.

Experience cross-platform friendliness

A universal solution for clearing the terminal using Python's shutil module has robust applications. Besides cleaning up your terminal, it can also effectively manage high-level file operations.

Clearing terminal with shutil

import shutil
shutil.get_terminal_size()  # Probing terminal dimensions like an astronaut!
shutil.rmtree('folder_name')  # Bid farewell to the directories and their contents


When aiming for seamless terminal management along with file operations, shutil is ace up your sleeve.

Beyond conventional terminal commands

Clearing up your workspace is cool. But why not explore beyond traditional terminal commands with Python?

Use GUI libraries

Ever thought of using GUI libraries, such as tkinter or PyQt? They can create graphical interfaces offering clear and refresh features without any terminal commands.

Integrate with IDEs

While working in an IDE or code editor, remember to utilize their specific in-built commands or shortcuts to clear the terminal or the output console.
