Subject: loopback.py Colab compatibility and bug fix

This code (suggested by @abvgdeabvgde2 ) literally does the same thing and it does not break with Python 3.9, making it helpful for Google Colab users (me included).
fixes #8927
Also a partial fix for #8902 but it does not resolve the unresponsive UI problem faced by @Archon332
