title: How to revert back to python 2.7?
body: <p>Whenever I ran <code>python --version</code> the result was 2.7 and 3.8 for <code>python3 --version</code>. I wanted to get 3.8 by running only <code>python --version</code> instead of <code>python3 --version</code> and after looking for the same on stackoverflow I did this</p>
  <pre><code>sudo rm /usr/bin/python
  </code></pre>
  <p><code>sudo ln -s /usr/bin/python3 /usr/bin/python</code></p>
  <p>and while it did what I wanted but now a lot of things are going haywire. Therefore, I want my system to go back to the way it was before.</p>
  <p>P.S. I wanted python to call python3 in the first place because whenever I would run <code>mkvirtualenv name</code> it would give me a warning that I am using python 2.7 and should switch to 3.8 but python 3.8 was already there on my computer and I thought maybe by doing the above mentioned I would get rid of the warning.</p>
