Firstly, I'm a relative beginner with Python, Linux, terminal and pyenv, so keep that in mind ;)

I learned that pyenv is a good way to manage multiple versions of Python in parallel between projects. Before I discovered that, I installed a couple versions of Python that I now would like to remove but I don't know how. I will reinstall them later using pyenv so everything's nice and neat.

I had a vague idea about which Python-versions I installed using `altinstall` in addition to the system: Python 3.7 and 3.9. My system (Linux Mint 20.1) came with Python 2.7 and 3.8 so I would like to leave those alone. Using the terminal command:

```
whereis python 

```

I get the following output:

```
python: 
/usr/bin/python3.8 
/usr/bin/python2.7 
/usr/bin/python3.8-config 
/usr/lib/python3.8 
/usr/lib/python2.7 
/usr/lib/python3.9 
/etc/python3.8 
/etc/python2.7 
/usr/local/bin/python3.7 
/usr/local/bin/python3.9-config 
/usr/local/bin/python3.9 
/usr/local/bin/python3.7m 
/usr/local/bin/python3.7m-config 
/usr/local/lib/python3.8 
/usr/local/lib/python3.7 
/usr/local/lib/python2.7 
/usr/local/lib/python3.9 
/usr/include/python3.8 
/usr/share/python

```

In conclusion, I would like to remove Python version 3.7 and 3.9 including related packages, without breaking my installation of Linux Mint 20.1, any advice? Thanks!
