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

Windows Spyder 4, Python 3.7:

• !cls
• cls
• cls()
• Ctrl + L
• clear
• clear()
• print(chr(27) + "[2J")
• print("\x1b[2J")
• clear-screen

Windows Terminal, Python 3.9:

• !cls
• cls
• Ctrl + L
• cls()
• print(chr(27) + "[2J")
• print("\x1b[2J")

Linux Terminal, Python 3.8:

• Ctrl + L
• clear

(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', '')
