Python Range

This lesson is part of Python · All levels

Summary

The range function produces a sequence of numbers that is very useful as a control of repetition. We can determine the starting value, the end limit, even the big jump between numbers. However, the range is not a list but a number-generating object, so it is memory-saving and often used in conjunction with the for.

Key points

Range(n) produces numbers from 0 to n - 1.
Start at the beginning and stop before the end.
The third argument is a jump between numbers.
The range is common, meaning the elements are generated when needed.
