How to make a nested for loop in Python

In this lesson I'll explain how to make a nested for loop in Python by a practical example.

What is a nested loop? It is simply an inner loop inside another outer loop.

Example

This script uses a simple nested loop

How does it work?

The outer loop prints the rows while the inner loop prints the columns.

• In each iteration of the outer loop (row), the program goes through a complete inner loop.
• In each iteration of the inner loop (column), the program prints the product between the row and the current column.

Here is the program output
