Original exception was:

That does not look like a fuzzy error. That looks like you changed the version of Python3, which broke apt. — user535733, Dec 05 '19 at 18:00
yes i changed it to python 3.7 but how can i fix that and keep using python 3.7? — Mahmoud H. Al-Ridini, Dec 05 '19 at 18:04
Does this answer your question? ModuleNotFoundError: No module named 'apt_pkg' error — Kulfy, Dec 05 '19 at 19:42

Your question is about how to upgrade Python3 without breaking apt as mentioned in comments by @user535733. You can just install several versions of python in parallel on your machine.

You can easily fond tutorials for that: https://www.freecodecamp.org/news/manage-multiple-python-versions-and-virtual-environments-venv-pyenv-pyvenv-a29fb00c296f/
