- Input the number from user.
- Initialise the product variable to 1.
- Use the for loop ranging from 1 till n+1 in order to multiply and find the factorial.
- Print the factorial of the number.
n= int(input("Enter the number you want to find the factorial of: ")) prod=1 for i in range(1,n+1): prod=prod*i print(prod)
