📌 Python for Exercise Five: Factorial | Step-by-Step Tutorial
🔢 Learn how to calculate the factorial of a number using Python! In this step-by-step tutorial, we'll break down the logic behind factorial calculations and implement them using Python. Whether you're a beginner or just looking to sharpen your coding skills, this video is for you!
🎯 What You'll Learn:
✅ What is a factorial? (n!)
✅ Different methods to calculate factorial (loop & recursion)
✅ Writing a Python program for factorial step by step
✅ Understanding the logic behind recursive functions
✅ Practical examples and explanations
📌 Code Used in This Tutorial:
python
Copy
Edit
Method 1: Using a loop
def factorial_loop(n):
result = 1
for i in range(1, n + 1):
result *= i
return result
Method 2: Using recursion
def factorial_recursive(n):
if n == 0 or n == 1:
return 1
return n * factorial_recursive(n - 1)
Example
num = 5
print("Factorial using loop:", factorial_loop(num))
print("Factorial using recursion:", factorial_recursive(num))
