Calculate Factorial Using Iterative Method

❮ Previous Next ❯

A Python program to compute the factorial of a number using an iterative approach.

Step-by-Step Explanation in Points:

Function Definition (factorial(num))
- A function is created to calculate the factorial of a number.
Initialize Factorial Variable (factorial_number = 1)
- A variable factorial_number is set to 1 to store the result.
Loop from 1 to num (inclusive)
- Use for i in range(1, num + 1).
- Iterates through all numbers from 1 to num.
Multiply in Each Iteration
- Multiply factorial_number by i in each loop iteration.
- This accumulates the factorial value.
Return the Final Result
- After the loop ends, return factorial_number.
User Input (num)
- Take input from the user and convert it to an integer.
Call the Function & Print the Result
- Call factorial(num) and print the calculated factorial.

Program:

def factorial(num):

    factorial_number = 1

    for i in range(1, num + 1):

        factorial_number *= i

    return factorial_number



num = int(input("Enter a number: "))

print(f"Factorial of {num} is:", factorial(num))
