Arrays are used to store mulitpule pieces of data in 1 variable. The only diffrence is that you need to use a [] instead of a (). arrays are used so that you can select 1 point of data in the array and show the use, or you can show them all of it. Just remeber that python arrays start at zero. so if you want to print the first point of your data you need to print('your array name'[0]).
