title: python compile script to "unreadable" form
body: <p>I would like to compile python script, so nobody will be able to easily read source (there is file inside and function to check some hashes - so I want to hide it). 
  I tried <code>py_compile.compile("script.py")</code> but when I open compiled file (.pyc) in plaintext editor, I can see some strings and function names in readable form. I need to prevent this so it should not be easily readable.</p>
  
  <p>What to use for this? 
  (I am on linux, python 2.7)</p>
