Introduction to Python

Range

If you're looking to loop through indices rather than the elements themselves, you'll want to get familiar with the range() function. range() produces a series of numbers and returns a range object. This function can accept 1, 2, or 3 positive number arguments.

When you provide just one argument, n, it returns all integers from 0 up to, but not including, n. For example, range(5) yields the numbers 0 through 4.

If you give the function two arguments, n and m, it returns all integers starting from n and going up to, but not including, m.

So, range(5, 10) will produce the numbers 5 through 9.

When you provide three arguments, n, m, and s, it returns integers starting from n and ending before m, but incrementing by s.

For instance, range(10, 30, 5) will give you the numbers 10, 15, 20, 25.
