Often, we want to create a list of consecutive numbers. For example, suppose we want a list containing the numbers 0 through 9:

my_list = [0, 1, 2, 3, 4, 5, 6, 7, 8, 9]

Typing out all of those numbers takes time and the more numbers we type, the more likely it is that we have a typo.

Python gives us an easy way of creating these lists using a function called range. The function range takes a single input, and generates numbers starting at 0 and ending at the number before the input. So, if we want the numbers from 0 through 9, we use range(10) because 10 is 1 greater than 9:

my_range = range(10)

Just like with zip, the range function returns an object that we can convert into a list:

>>> print(my_range)
range(0, 10)
>>> print(list(my_range))
[0, 1, 2, 3, 4, 5, 6, 7, 8, 9]
