[Python Programming Basics to Advanced] : while Loop in Python | Lab 12

This Python programming playlist is designed to take beginners with zero programming experience to an expert level. The course covers installation, basic syntax, practical scenarios, and efficient logic building. The course material includes PDF handouts, review questions, and covers a wide range of topics, from data types to advanced functions like Lambda and Recursive functions, Generators, and JSON data parsing.

In this lesson we will continue our discussion on for loop and will explore that we can have multiple for loops in a program. We can have a for loop inside another for loop, known as Nested for loop.
