Use python 3.6 packages in python 3.9

Hi,
Since Python 3.6 is out of support, I wanted to switch to Python 3.9, but there are only few packages in repository for Python 3.9. Is there any way to use Python 3.6 packages in Python3.9? or do I have to rely on “pip” installation?
I am using openSUSE leap 15.3.

Have a look at the “anaconda” python system. It is a self-contained python environment that includes all necessary auxiliary packages. It currently runs python 3.9. It runs as a user. It redundantly installs many packages into it’s user directory that are also installed in system directories. So if disk space is an issue might need a hard look. Also includes pycharm ide. Handles package installs and updates through cli or through a gui.
