title: Reoccurring Python error that doesn't make much sense
body: <p>I keep getting this error while working in a script: </p>
  
  <pre><code>'python' is not recognized as an internal or external command,
  operable program or batch file.
  </code></pre>
  
  <p>Isn't this an error you'd see in terminal? I'm in Atom text editor. On top of that, it was working a few minutes ago (i.e. giving me errors about my actual code) and I've been working on it with no problem all day long.</p>
