This video provides an introduction to lambda functions in Python. Specifically, it covers:
-Reviewing what a function and how a function refers to an object
-What a lambda function is and why you would use one
-Lambda function syntax
-Several examples of lambda functions, including map, filter, and reduce
-Practice problems!!

Nice tutorial about lambda which brought to my attention that I don't really use map, reduce or filter a lot.
I'm wondering if using them is slower or faster than using list comprehensions. Will have to experiment a bit.
