AssertionError when trying the sys module in python

[Larz60+]

Does that work in IDLE? Because anything for color except sys doesn't work on IDLE, as far as I know.

My opinion:
Get rid of IDLE and pick a real IDE.
Even though IDLE is packaged with python, it's not a good, nor in my opinion a real IDE.

VSCode is very good and used by many on this forum, as is PyCharm
