I do get the fact that range() is a shortcut for generating a list, but I don’t get how the output becomes(How I think of it random)when there are three or more numbers in the parentheses of the function. This isn’t really a forum for a answer. I just want a good explanation of my problem.

# Range() Function Help!

The `range()`

function allows you to get specify with the *range of numbers* that you want to create.

If all you want is a set of numbers from 0 to n, then you do `range(n)`

where `n`

- 1 is the largest number in the dataset. For example, `range(10)`

gives you a list of `[0,1,2,3,4,5,6,7,8,9]`

.

But what if you want to start a different number? You don’t want to start your number set at `0`

. Maybe you want to start at 10. Python gives you a way to do that:

`range(start, stop)`

where the `start`

is say `10`

in our example and let’s say you want to go to `20`

. Then you’d do `range(10, 20)`

which gives you `[10, 11, 12, 13, 14, 15, 16, 17, 18, 19]`

.

Still with me?

Let’s say that you want to increment the numbers by say 5. So what you want is a number set that starts with 5 and goes to 30 but is only increments of 5s.

`range(5, 31, 5)`

where the last number is the `step`

. That will give you `[5, 10, 15, 20, 25, 30]`

.

You can do negative numbers too and if negative steps. Go check out the Python documentation as it has some good examples for you:
