Factorial of a Number in Python

Write a Program in Python to find the Factorial of a Number

GivenNumber = int(input("Enter a Number: "))    
factorial = 1    
if GivenNumber < 0:    
   print(" Sorry! The Factorial does not exist for negative Numbers")    
elif GivenNumber == 0:    
   print("Please Note that The factorial of 0 is 1")    
else:    
   for loopVariable in range(1,GivenNumber + 1):    
       factorial = factorial*loopVariable    
   print("The factorial of",GivenNumber,"is",factorial)

GivenNumber = int(input("Enter a Number: "))

factorial = 1

if GivenNumber < 0:

print(" Sorry! The Factorial does not exist for negative Numbers")

elif GivenNumber == 0:

print("Please Note that The factorial of 0 is 1")

else:

for loopVariable in range(1,GivenNumber + 1):

factorial = factorial*loopVariable

print("The factorial of",GivenNumber,"is",factorial)

Output Please Enter a Number: 4 The factorial of 4 is 24

Factorial of a Number using Recursion in Python

# Python program to find  factorial of given number 
import math  
def fact(GivenNumber):  
    return(math.factorial(GivenNumber))  
  
num = int(input("Enter the number:"))  
Factorial = fact(num)  
print("Factorial of", num, "is",Factorial)

# Python program to find factorial of given number

import math

def fact(GivenNumber):

return(math.factorial(GivenNumber))

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

Factorial = fact(num)

print("Factorial of", num, "is",Factorial)

Output Enter the number:7 Factorial of 7 is 5040
