What do I have for you?

• Introduction to functional programming
• Daily usage (but do you know about them?)
• What Python has to offer
• Extending the standard offering, Python libraries

Paradigms of programming

• Procedural
• Object oriented

• Logic
• ...

...and Python is a mixed bag!

What is a functional program?

I use functions all day...

Think mathematically, y = f (x)

Functions in Python

Python has first-class functions

Functions can take in functions as arguments

Functions can return functions

Time to get some action!

*demo on first order function*

*introduction to lambdas, anon functions*

*built-ins, filter, map, etc.
though list comprehension (yay!)*

import functools

*examples on partial, Haskell reference*

*decorators*

Cons of using Python

• Purely functional hard to achieve...
• Have an intuition on where to use

Hope you enjoyed!
