Procedural Python
● Code executed sequentially
● Easy to understand
● Faster to implement
● Natural
● Program lines can be very long
● Need a way to architect to:
○ Manage our code physically
○ Manage our application logic

Efficient code: using external functions (library)
● Consider a module to be the same
as a code library.
● A file containing a set of functions
you want to include in your
application.
