To keep a computer doing useful work we need repetition, looping back over the same block of code again and again. It is the ability to execute a certain code repeatedly. That is the very basic structure of a for loop. In this section, we will see how loops work in python. Looping is simply a functionality that is commonly used in programming for achieving repetitive tasks.
