title: How to install python 3.6.10 alongside presinstalled 3.8.2
body: <p>I recently installed Pop!_OS on my laptop for development purposes, but i found out the version of python installed is 3.8.2, which unfortunately doesnt support versions of tensorflow below 2.0. I need to use tensorflow 1.14 for my work and this is not possible with python 3.8.</p>
  
  <p>Im willing to use python 3.6 in a virtual environment or have it alongside 3.8 in my laptop. Im rather new to linux so please excuse any mistakes. Thanks in advance!</p>
