Introduction to Python

RangeRange

If you don't want to iterate over elements but want to iterate over indexes, then you need to learn the range() function. range() returns a range object representing a set of numbers. This function can receive 1, 2, or 3 arguments (positive numbers). Suppose the function receives only one argument, n. In that case, it will return all the integers from 0 to n (not including n itself). For instance, range(5) will generate integers from 0 to 4.

If the function receives two arguments, n and m, it will return all the integers from n to m (not including m). For instance, range(5, 10) will return integers from 5 to 9.

If the function receives three arguments, n, m, and s, it will return integers from n to m with the step of s (not including m). For example, range(10, 30, 5) will return integers 10, 15, 20, 25.
