Module VS Package

• Module: single python script
• Package: collection of modules

PATHS

SYS.PATH

• The python interpreter tries to look for the directory containing the module we are trying to import in sys.path. It is a list of directories that Python will search once it is done looking at the cached modules and Python standard library modules.
• The output from sys.path will always contain the current directory at index 0! The current directory being the one where the script being run resides.

PYTHONPATH

• PYTHONPATH is an environment variable which you can set to add additional directories where python will look for modules and packages
