title: Command 'python' not found
body: <p>I am trying to install python 3.8 on ubuntu 18.04.</p>
  <pre class="lang-sh prettyprint-override"><code>python ––version
  sudo apt update
  sudo apt install software-properties-common
  sudo add-apt-repository ppa:deadsnakes/ppa
  sudo apt update
  sudo apt install python3.8
  python ––version and it gives me &quot;sudo apt install python3
  sudo apt install python
  sudo apt install python-minimal. You also have python3 installed, you can run 'python3' instead.
  </code></pre>
  <p>How do I install?</p>
