Python factorial program with example
In this tutorial, you will learn how to write python factorial program. If you want calculate factorial of 5, you have to multiply values from 5 to 1 .
Example: 5! = 5*4*3*2*1
print("Python factorial program")
num = int(input("Enter a number: "))
fact = 1
if num < 0:
print("Sorry, factorial does not exist for negative numbers")
elif num == 0:
print("The factorial of 0 is 1")
else:
for i in range(1,num + 1):
fact = fact*i
print("The factorial of",num,"is",fact)
Output 1:
Python factorial program
Enter a number: 5
The factorial of 5 is 120
Output 2:
Python factorial program
Enter a number: 10
The factorial of 10 is 3628800
Output 3:
Python factorial program
Enter a number: 10
