title: Importing requests in python gives error
body: <p>I have a small python (2.7) script that works with several threads. One of the threads will read a global list and post an https post request for each one of the entries of this list.</p>
  
  <p>For doing that I saw that the best way is to use python requests module. I have installed it with pip (no problem with that, it is placed in ...Python/2.7/site-packages/requests/...), but, when I import this module in my script, I get an error.</p>
  
  <p>I have created another script with just one line (import requests) to reproduce the error, and I get this:</p>

  <p>Am I doing something wrong? Didn't I installed the module in the proper way?</p>
