Program to find factorial of a number in Python

The program to find factorial of a number in python is as follows:

 

# Owner : TutorialsInhand Author : Devjeet Roy

n = int(input("Enter number: "))
fact = 1

for i in range(n,0,-1):
    fact *= i

print("The factorial is:",fact)

The output of python program to find factorial of a number is as follows:

 

PS C:\Users\DEVJEET\Desktop\tutorialsInHand> python code.py
Enter number: 5
The factorial is: 120

Few important points about this problem:

1. Firstly, we ask theuser to input any number and then we convert to its int equivalent.

2. We initialize the "fact" variable as 1.

3. Then, we start a loop from n and deduce to 1 (as zero is exclusive) and keeping multiplying the numbers with their previous product.

4. Finally, we get the factorial of the number.
