title: Importing modules from different folder python for unknown path
body: <p>I have been working on a python project and I am new to it.
  I have made a small library for my project in which I have several different modules doing different tasks.</p>
  
  <p>For example: I have 5 modules namely add, subtract, multiply, divide and root.
  I call all these <code>.pyc</code> files into my <code>main.py</code> file and my code runs properly <strong>if all of them are in the same folder</strong>.</p>
  
  <p>Now, I want to store my <code>main.py</code> at: <code>D:\project\main.py</code>
  and these 5 <code>.pyc</code> files at : <code>D:\project\Lib\</code> (In the Lib folder)</p>
  
  <p>I found a solution as to mention the path of the folder Lib into the code but I can not do so as I need to submit the code somewhere and if they try to run this on their PC, it might not import these files.</p>
  
  <p>What would be the possible solution to this?</p>
