```I'd do it like this... And there's probably an even quicker way, if
you really sat down and thought about it.

n = int(raw_input("Number: "))
x = n-1
while x > 1:
n *=x
x -=1
print n

The reason why it isn't working is because of
"
while x > 1:
x -= 1
"
When your program hits this point it stays in the while loop,
subtracting 1 from x each time, but not multiplying anything anymore,
until it hits break. So your program does this.

Number: 4
n = 5
x = 4
t = 20
x = 3
x = 2
x = 1
BREAK.

Cheers!
