Comprehensions are an effective way to build lists using a notation reminiscent of set theory.
They are one of the nicest concepts Python borrowed from Functional programming, and they allow you to write code that's both compact and fast. In this video I show you how to create a comprehension, and how to use the "if" keyword as a filter to specify conditions that the elements of the final list must satisfy.
