title: ImportError: No module named functions
body: <p><a href="https://i.stack.imgur.com/vEEvY.png" rel="nofollow noreferrer">Image</a></p>
  
  <p>I don't know what am I doing wrong here. I am importing the module from the <code>functions</code> package in the <code>tests</code> package. I tried every method but couldn't solve this problem while I tried to run <code>valid_test.py</code></p>
