Hi Taylor.

Well, the way I understand List Comprehensions is a simpler way to create a list based on another list.

Think about this example:

original_list = [ 1 , 2 , 3 , 4 , 5 ]

You want another list that take each value of the original_list and multiply it by 2. So you want:

original_times_two = [ 2 , 4 , 6 , 8 , 10 ]

There are many ways to get this result. Using Loops is the most basic one. But List Comprehension is much simpler.

So, thinking about the sintax you mentioned, let’s break it into pieces:

**operation_on_i for i in some_list**

**some_list** is the original_list. Is the list that you are using the values.

**i** is a temporary variable. The **for** will make **i** assume each value of the original_list, one at a time.

**operation_on_i** is basically what you want to do with each value assumed by **i**

All of that goes inside the list you want to create.

Getting back to my example, this is what you should do:

original_times_two = [ i * 2 for i in original_list ]

I hope I helped and I am sorry if it was a bit confusing. If you need anything else, just ask.
