Lambda functions in Python

Note: I use Python 3, but most of these should work in Python 2 too.

Intro

Lambda functions are also known as anonymous functions and are typically passed as arguments to other functions. Notable examples are the map(), reduce(), filter() built-in functions which require a function to be passed as an argument.
