In the previous activity, you created an ndarray called ax. It was an array of SubplotAxes objects. You accessed one SubplotAxes by using an index in square brackets: ax[0]. You probably recognize that this is the same syntax used to access an element of a list. However, the ndarray is different than a list; it is an array.

As a result, if we have an M×N array in Python, its indices go from 0 to M-1 on the first axis and 0 to N-1 on the second. It takes a bit of getting used to, but one way to remember the rule is that the index is how many steps we have to take from the start to get the item we want.

By now we know that Python likes to start counting with zero 0 as the “first” item as we have seen previously with range() for example. In the same way, items in the list are indexed starting with zero 0; the last item is referenced as -1.

Integer defines the type of numbers that can be stored, numbers is the name of the array, and [10] is how many numbers can be stored. In most languages, the first element is assigned the subscript of 0, so the above array actually runs from 0 to 9.

The solution offered by Python is to store lists and tuples into arrays. Assigning arrays. Names for arrays follow the same rules as those defined for scalar variables. We store a list into an array the same way we store a scalar into a scalar variable, by assigning it with =: for a tuple, or. for a list.
