The question is simple enough, but I can't find the answer. Is there an operator or something similar that clears the Blender System Console history? I would also be willing to create an operator type script to "purge" the console. It would be interesting to see if it's possible, or I'm just "delirious". Restarting blender doesn't take long, but it would be nice to have a "Button" to do this.

  • $\begingroup$ Do print('\f') with no space. Its a control character like '\n' for newline $\endgroup$

  • $\begingroup$ Ok I tried it from a Blender Text script and from Blender's python console. Weird symbols come up, but I don't really understand what this is for. $\endgroup$

  • $\begingroup$ Just like \n \t and other text control stuff, where \f stand for form feed to indicate output go on next page. Which is not clear console for sure $\endgroup$

Below is an example add-on that adds a button to the text editor for this purpose. Clearing the console is done with the platform specific commands cls for Windows and clear for Linux and macOS. Both are executed through os.system(command)

Text Editor Header

bl_info = {
    "name": "Clear System Console",
    "author": "Robert Guetzkow",
    "version": (1, 0, 0),
    "blender": (2, 81, 0),
    "location": "Text Editor Header",
    "description": "Clear the system console.",
    "wiki_url": "",
    "category": "Text Editor"}

import bpy
import os

class CLEARCONSOLE_OT_clear(bpy.types.Operator):
    bl_idname = "clearconsole.clear"
    bl_label = "Clear System Console"
    bl_description = "This operator clears the system console."
    bl_options = {"REGISTER"}

    def execute(self, context):
        if os.name == "nt":
        return {"FINISHED"}

def draw(self, context):

classes = (CLEARCONSOLE_OT_clear,)

def register():
    for cls in classes:

def unregister():
    for cls in classes:

if __name__ == "__main__":

You can use os.system and call cls or clear:

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

sort of snippet:

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

cls() #this function call will clear the console

As of 2021, there is an operator for this.

  1. Clear command history only:
bpy.ops.console.clear(scrollback=False, history=True)
  1. Clear command history and scrollback history:
  1. Clear scrollback history only:
