([msg=18020]see Facorial Calculator[/msg])

As stated in my previous post, I have been bored lately, writing occasionally useful code. This time I have written a very simple collection of lines that calculates the factorial of a number. This code is useful for calculating the total number of possibilities that a word list generator can produce.

- Code: Select all
`a = long(raw_input("Number: "))`

b = a

factorial = a

while a > 1:

a -= 1

factorial = factorial * a

print "The factorial of",b,"is:",factorial

Factorial:

Mathematics. the product of a given positive integer multiplied by all lesser positive integers: The quantity four factorial (4!) = 4 · 3 · 2 · 1 = 24.

Symbol: n!, where n is the given integer.
