   136 1. Look at the python documentation (from the web) and learn how to

   137    make a folder containing some python files into a module.

   138 

   139    Answer: Add a file named __init__.py

   140 

   141 2. We know that ``sys.path`` has the paths in which Python checks for

   142    a module, when it is imported. Suppose you have a package ``utils``

   143    in some location on your disk, which is not on the python path, how

   144    will you import it?

   145 

   146    Answer: Append that path to the ``sys.path`` variable.
