Clear PyCharm Run Window

Question

Is there a way to clear the "Run" console in PyCharm? I want a code that delete/hide all the print() made previously. Like the "clear_all" button, but without having to press it manually.

I have read that there is a way to do it in a terminal with os.system("cls"), but in PyCharm, it only adds a small square without clearing anything.

Also, I don't want to use print("\n" *100) since I don't want to be able to scroll back and see the previous prints.

How to

1. Download this package https://github.com/asweigart/pyautogui. It allows python to send key strokes.

You may have to install some other packages first

If you are installing PyAutoGUI from PyPI using pip:

Windows has no dependencies. The Win32 extensions do not need to be installed.

OS X needs the pyobjc-core and pyobjc module installed (in that order).

Linux needs the python3-xlib (or python-xlib for Python 2) module installed. Pillow needs to be installed, and on Linux you may need to install additional libraries to make sure Pillow's PNG/JPEG works correctly. See:

2. Set a keyboard shortcut for clearing the run window in pycharm as explained by Taylan Aydinli

1. CMD + , (or Pycharm preferences);

2. Search: "clear all"; Double click ->

3. Add keyboard shortcut (set it to CTRL + L or anything)

4. Enjoy this new hot key in your Pycharm console!

3. Then if you set the keyboard shortcut for 'clear all' to Command + L use this in your python script

    import pyautogui
    pyautogui.hotkey('command', 'l')
   

Example program

This will clear the screen after the user types an input.

If you aren't focused on the tool window then your clear hot-key won't work, you can see this for yourself if you try pressing your hot-key while focused on, say, the editor, you won't clear the embedded terminals contents.

PyAutoGUI has no way of focusing on windows directly, to solve this you can try to find the coordinate where the run terminal is located and then send a left click to focus, if you don't already know the coordinates where you can click your mouse you can find it out with the following code:

import pyautogui
from time import sleep
sleep(2)
print(pyautogui.position())

An example of output:

(2799, 575)

and now the actual code:

import pyautogui

while True:
    input_1 = input("?")
    print(input_1)
    pyautogui.click(x=2799, y=575)
    pyautogui.hotkey('command', 'l')

In Pycharm:

1. CMD + , (or Pycharm preferences);
2. Search: "clear all";
3. Double click -> Add keyboard shortcut (set it to CTRL + L or anything)
4. Enjoy this new hot key in your Pycharm console!

Answer 3

Pycharm Community Edition 2020.1.3

You can right click anywhere above the current line on the console, and choose the "Clear All" option. It'll clear the console

Answer 4

Easy Method: Shortcut: Control K, Right click on terminal and clear Buffer

Answer 5

There's also another way of doing it using the system class from os. All you need to do is have this code:

from os import system, name


# define our clear function
def clear():
    # for windows the name is 'nt'
    if name == 'nt':
        _ = system('cls')

    # and for mac and linux, the os.name is 'posix'
    else:
        _ = system('clear')

# Then, whenever you want to clear the screen, just use this clear function as:
clear()

However, in order for this functionality to work in pycharm, you need to enable "Emulate terminal in output console". You can find this under edit configuration of the file where you want to use the clear function, then it's under Execution option. Here's a screenshot: pycharm screensho

Answer 6

You could just do a ("\n" * 100000000), so it'll be impossible to scroll back.

Answer 7

In PyCharm terminal you can type 'cls' just like in linux terminal.

For Python Console (where you see the output) assign a shortkey for "clear all" in File -> Settings -> Keymap -> Other -> "Clear all"

You can also click somewhere on the PythonConsole -> Right button -> clear.

Hope it helps

Answer 8

Sorry to say this, here the main question is how to do it programmatically means while my code is running I want my code to clear previous data and at some stage and then continue running the code. It should work like reset button.

After spending some time on research I solved my problem using Mahak Khurmi's solution https://stackoverflow.com/a/67543234/16878188.

Answer 9

Just click the trash can icon to the left of the command window and it clears the command history!

Answer 10

In PyCharm 2019.3.3 you can right click and select "Clear All" button.This is deleting all written data inside of the console and unfortunately this is manual.

Answer 11

I just relised that instead of going to the trouble of setting up a shortcut, you could just set up a command using PyAutoGUI to click on the trash bin on the side of the window e.g

note, to install pyautogui click on the end of the import pyautogui line, then press alt+enter and click install pyautogui.

import pyautogui

# to find the coordinates of the bin...
from time import sleep
sleep(2) # hover your mouse over bin in this time
mousepos = pyautogui.position() gets current pos of mouse
x,y = mousepos # storing mouse position 
print(mousepos) # prints current pos of mouse

# then to clear it;
pyautogui.click(x, y) # and just put this line of code wherever you want to clear it

(this isn't perfect thanks to the time it takes to run the code and using the mouse, but it is reasonable solution depending on what you are using it for.) I hope this answer is helpful even though this is an old question.

Answer 12

If you edit the run configuration you can enable "emulate terminal in output console" and you can use the os.system("cls") line and it will work normally.
