How do Python modules work
	>>> import amodule • If the module was not loaded previously: 1. Find  amodule.py among PYTHONPATH 2. If necessary: byte-compile (amodule.pyc) 3. Execute the code and create a module object (essentially a dictionary of global variables) 4. Store the module object • When we have a module object, bind that module object to the name ‘amodule’
