Practical Python: Learn Python Basics Step by Step- Python 3 - While Loop

The video tutorial explains the use of for and while loops in Python. It begins with an introduction to loops, followed by a detailed explanation of while loops, including a practical example using a counter. The tutorial then compares for and while loops, discussing when to use each type. The key takeaway is that for loops are used when the number of iterations is known, while while loops are used when the condition to continue is external to the loop.

When should you use a for loop instead of a while loop?

Describe a scenario where a while loop would be more appropriate than a for loop.
