Python tutorial on the difference between the filter() function and list comprehensions.
We learn about using filter() with lambda and list comprehensions with lambda.
We run speed tests, chain functions, compare advantages of each, and determine if you should use filter or list comprehensions for iterating in Python. We also discuss what Guido prefers.
