From now on, I’m going to be using list comprehension when it is more convenient so I want to give a quick review if you are still confused how it works.

The set up of list comprehension is:

[A for B in C]

A is the function that you want to apply to whatever variable you are getting, B is the way you denote the variable you are using the function on, and C is the array you are pulling variables.

So if you had an array yourArray = [1,2,3,4] and wanted to double it you would write:

[x*2 for x in  yourArray]
