We can use range to generate more interesting lists.

By default, range creates a list starting at 0. However, if we call range with two arguments, we can create a list that starts at a different number. For example, range(2, 9) would generate numbers starting at 2 and ending at 8 (just before 9):

>>> my_list = range(2, 9)
>>> print(list(my_list))
[2, 3, 4, 5, 6, 7, 8]

With one or two arguments, range will create a list of consecutive numbers (i.e., each number is one greater than the previous number). If we use a third argument, we can create a list that “skips” numbers. For example, range(2, 9, 2) will give us a list where each number is 2 greater than the previous number:

>>> my_range2 = range(2, 9, 2)
>>> print(list(my_range2))
[2, 4, 6, 8]

We can skip as many numbers as we want! In this example, we’ll start at 1 and skip 10 between each number until we get to 100:

>>> my_range3 = range(1, 100, 10)
>>> print(list(my_range3))
[1, 11, 21, 31, 41, 51, 61, 71, 81, 91]

Our list stops at 91 because the next number in the sequence would be 101, which is greater than 100 (our stopping point).
