title: Python modules not found over terminal but on python shell, Linux
body: <p>I have installed ubuntu on my laptop and i have installed python, after installing python2.7.5 i was trying to run a python script on terminal, but it said module no found, i started to download all the modules but it still said module not found. After upgrading to python2.7.9 it still said same so i installed python iddle shell which is importing the modules correctly. </p>
  
  <p>Why is it happening ? why is it working on the python shell but not on terminal. terminal is only recognizing modules like sys, os.. and some built-in modules but not the installed. I would appreciate the help. (I just started to use linux)</p>
