Factorial Program in Python: Python Program to Find Factorial of a Number

Simple python program to find the factorial of a number. A factorial of a number is the product of number less than or equal to n.
Factorial Program in Python: In this post you will learn a Python program to find factorial of a number.

What is Factorial of a Number?

  • Factorial of a number is the product of all whole number less that or equal to n.
  • Factorial of a number is denoted by n!.\
  • For example factorial of 4 is denoted by 4! which is equal to 4✕3✕2✕1 = 24.
  • Always remember factorial of 0! is 1.

Factorial Program in Python

Write a Program in Python to Find Factorial of a Number:

 Program 
c = 1
n = int(input("Enter the Number\n"))
for i in range(1, n+1):
    c = c*i
print("Factorial of", n, "is", c)

Output 
Enter the Number                                                                                                              
5                                                                                                                             
Factorial of 5 is 120 

The above program is a Factorial program in python using For loop.
