3.21 – Count Number of Digits | Python Programming – New Series

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

In this class (3.21), we continue with digit-based number programs and solve an important problem:

👉 Write a program to accept a number and count the total number of digits.

In this video, I have:

✔ Written the expected output clearly
✔ Explained the problem statement properly
✔ Written the complete program
✔ Performed a detailed dry run step-by-step
✔ Executed the program and verified the output

🎓 What You’ll Learn in This Video

• Accepting input from the user
• Understanding digit counting logic
• Using while loop effectively
• Using integer division (//)
• Working with counter variable
• Performing step-by-step dry run
• Writing clear and logical programs

🧠 Program: Count Number of Digits

Example:

Input: 4589

Process:
Digits → 4, 5, 8, 9

Output:
Total digits = 4

Logic

✔ Accept a number from the user
✔ Initialize count = 0
✔ Use while loop until number becomes 0
✔ Remove last digit using // operator
✔ Increment count for each iteration
✔ Display total count

🧠 Key Learning Point

Digit counting is based on the idea that:

✔ Each division by 10 removes one digit
✔ Loop runs until the number becomes 0
✔ Count increases with each step

Also, while loop is used because:

✔ Number of digits is not known in advance
✔ Loop continues until condition becomes false

🎯 Why This Video Is Important

This program is very important because it helps students:

• Understand digit processing clearly
• Strengthen loop control
• Build foundation for advanced number programs like:

- Reverse number
- Palindrome
- Armstrong number

These concepts are frequently used in exams and coding interviews.
