title: How to properly perform code coverage of every python file in a repo?
body: <p>I'm using this library <a href="https://coverage.readthedocs.io/en/v4.5.x/cmd.html" rel="nofollow noreferrer">https://coverage.readthedocs.io/en/v4.5.x/cmd.html</a></p>
  
  <p>There are bunch of files and directories in a repo</p>
  
  <p>I'm running bash script to interate through every python file and perform <code>coverage run a.py</code></p>
  
  <p>Is there any way to run a summarized result? Maybe create a big XML file as a summary?</p>
