3.2 – While Loop Program: Print Numbers from 5 to 1 | Python Programming – New Series

Описание: Welcome to the Python Programming – Complete Course (New Series) by Burle Sharma.

In this class (3.2), we continue learning the while loop by solving a new problem.

Here, I have:

✔ Written the expected output
✔ Explained the logic step-by-step
✔ Performed a dry run
✔ Executed the program using Python

The program prints numbers from 5 to 1, helping you understand how a while loop works when values decrease instead of increase.

This video strengthens your understanding of loop conditions, initialization, and decrement operation.

🎓 What You’ll Learn in This Video

• Writing expected output before coding
• Printing numbers in reverse order
• Using while loop with decrement
• Importance of initialization, condition, and update
• Step-by-step dry run of while loop
• How loop termination happens
• Execution and verification of output

🧠 Key Learning Point

To write a correct loop, always remember:

✔ Initialization – where the loop starts
✔ Condition – till when the loop runs
✔ Update – how the value changes

Dry run helps you clearly see how the value changes in each iteration and avoids infinite loops.

Understanding reverse looping is very important for future logic building.
