Best ResponseYou've already chosen the best response.0In python, the colon is the slicing operator, so it returns the elements between 0 and 1, including the element in index 0 and excluding the element in 1

Best ResponseYou've already chosen the best response.2a[0] returns the first element of the list a (we start counting at 0). a[0:1] returns all the elements in a from 0 up to but not including 1. Let's say I had a list x = [5,10,15,20,25]. x[1] would return 10. x[4] would return 25 x[5] would return an error, because x[5] is the sixth element, and there isn't one. x[2:4] would return [15,20]...it returns element 2, element 3, but not element 4.
