How make function factorial?

Answer 1

# Iteratively:
def IterativeFactorial(x):
if x==0 or x==1:
return 1
fact = 1
for i in range(2, x+1):
fact *= i
return fact

# Recursively:
def RecursiveFactorial(x):
if x==0 or x==1:
return 1
return x * RecursiveFactorial(x-1)

# test, should print out 6! ==> 720
print(IterativeFactorial(6))
print(RecursiveFactorial(6))

Answer 2

def factorial(x):
d = 1
for x in range(1,x + 1):
d = d * x
print(d)

Answer 3

Factorial: Multiply n * n-1 * n-2 ... 2 (ex. 5*4*3*2)
