This means that there's no such directory `../input/`. Because that is a 
relative path, it is important that when you invoke Python that it is 
_running_ in the right directory for that path to work.

Try putting this:

     import os
     print(os.getcwd())

before the `for...` line. That will tell you the current working 
directory Python is using, and hopefully that will make clear why the 
relative path is not working - the relative path must be valid from that 
directory from `os.getcwd()`.
