How to clear the screen of Interactive IPython console from Python code

Question

I have just migrated from Jupyter to Spyder. On the left of the screen there is a console that shows the output. When I rerun the code it keeps adding new lines. I want to start with a new screen. How?

PS1: When I go to the IPyhton console and write cls or clear, it works. But I want to do that from Python code. The latter doesn't recognize that command, but IPython console does!

PS2: I've tried

import os 
os.system('cls')  # on windows

It didn't work. It shows a CMD window for a moment and vanishes. But the console window in Spyder still shows the old errors, besides the new ones.

Answer 1

( Spyder maintainer here ) There are two ways to get what you want:

1. You can go to the menu Run > Configuration per file and select the option called Execute in a dedicated console . That option will clean your console after every execution.

2. Add the following code to your file:

    from IPython import get_ipython get_ipython.run_line_magic('clear', '')
