3.9 – Perfect Number Program | Python Programming – New Series

Welcome to the Python Programming – Complete Course (New Series) by Burle Sharma. In this class (3.9), we learn how to write a program to: 👉 Accept a number from the user 👉 Check whether the number is a Perfect number or not In this video, I have: ✔ Written the expected output clearly ✔ Explained the problem statement properly ✔ Performed a detailed dry run step by step ✔ Executed the program and verified the output This program strengthens your understanding of factor logic and conditional statements. 🎓 What You’ll Learn in This Video • Accepting user input in Python • Understanding what a Perfect number is • Using loop to find proper factors • Using accumulator (sum variable) • Applying conditional statements • Dry run for better logical clarity • Execution and output verification 🧠 Key Learning Point A Perfect number is a number whose sum of proper factors (excluding the number itself) is equal to the number. Example: 6 → Factors: 1, 2, 3 Sum = 1 + 2 + 3 = 6 So, 6 is a Perfect number. ✔ Loop runs from 1 to n-1 ✔ Check divisibility using % operator ✔ Add factor to sum if divisible ✔ Compare sum with original number ✔ If equal → Perfect number ✔ Else → Not a Perfect number This concept builds a strong base for: • Factor-based programs • Prime and Composite logic revision • Number-based problem solving • Competitive coding fundamentals #Python #PythonProgrammingNewSeries #BurleSharma #PerfectNumber #NumberPrograms #WhileLoopPython #PythonBeginners #PythonModulusOperator #PythonDryRun #LoopPrograms #Geecoding #PythonClass9
