You can create a list of numbers automatically using a range. For example:

list(range(1, 10))

That will output:

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

As you can see we just needed to specify the list boundaries inside range(). So, we specified 1and 10. Note that 10 is not included in the list. The generated list always runs up to one number before the upper number. In our example it goes up to 9 since the upper number is 10.

You can also specify a step as a third argument:

list(range(1, 10, 2))

That will output:

[1, 3, 5, 7, 9]

So, the count happens every two items starting from 1 and ending at 9.
