What is for loop

A for loop is a control flow statement to iterate over a sequences such us: list, dictionary, tuple, string or set.

Note: Python like most other programming languages counts from 0 and ends at the end of range. To print indeed numbers from 1-10 you need t0 tell Python start and end points.
