title: How to protect my Python code before distribution?
body: <p>I have written a python code which takes an input data file, performs some processing on the data and writes another data file as output. </p>
  
  <p>I should distribute my code now but the users should not see the source code but be able to just giving the input and getting the output!
  I have never done this before. </p>
  
  <p>I would appreciate any advice on how to achieve this in the easiest way.</p>
  
  <p>Thanks a lot in advance</p>
