Broke Python Whilst Trying to Upgrade 3.8 to 3.9

Here is what happened; I tried to upgrade python3.8 to 3.9; my goal was to Install python3.9 and then force my system to start using 3.9 instead of the current 3.8.

Then I found thsHow to Upgrade to Python3.9

Ignorantly without reading the comments, I jumped into my terminal and started executing the install and update-alternatives commands; at the end of the article; I discovered that I wrote a small python program and discovered that I could not run it.

That was when I decided to go through the comments, and discovered that some dependencies were missing; having tried to install dist-utils for 3.9; my system did not allow any install, kept saying it's available or something so I ignored and decided to quickly go back to my 3.8 having read some articles here warning against messing with default python installations.

Initially, my fear was that I have broken the default python installation; even though I never attempted removing it, so I decided to switch back to the old 3.8 I had working well.

I did was simply following the same article which gave room for switching between the python versions and switched back to 3.8; now it appears I'm fine.

My question is how to setup the installed 3.9 so that I can have it function properly?

You need to set up a python environment. Don't change the installed version of python on your system. You will break all of the software that requires the version in repositories for your Ubuntu release. See: https://askubuntu.com/a/865644

Thanks, I have already done that by using built-in venv module and then Conda. trying to install Anaconda Navigator now.

Most people don’t grasp that asking a lot of questions unlocks learning and improves interpersonal bonding. In Alison’s studies, for example, though people could accurately recall how many questions had been asked in their conversations, they didn’t intuit the link between questions and liking. Across four studies, in which participants were engaged in conversations themselves or read transcripts of others’ conversations, people tended not to realize that question asking would influence—or had influenced—the level of amity between the conversationalists.
