Python How to Find the Factorial of a Number

[AplexTM 3]

# Python program to find the factorial of a number provided by the user.

# change the value for a different result
num = 7

# uncomment to take input from the user
#num = int(input("Enter a number: "))

factorial = 1

# check if the number is negative, positive or zero
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):
      factorial = factorial*i
  print("The factorial of",num,"is",factorial)

# way 1

 

def factorial(num):

   if num == 1:

       return 1

   else:

       return num * factorial(num - 1)

print(factorial(n))

 

# way 2

 

fac = 1

for i in range(1,n + 1):

   fac *= i

 

 

print(fac)

 

I'll add more soon XD ,these were the only ones i conjure up in 3 minutes
