true so unless the factorial is calculated (second portion of AND statement)
return will not give factorial. the second portion is recursive call to

On Wed, Oct 27, 2010 at 11:55 AM, Geob
I am a beginner in Python and would ask for a help.
I was searching for smaller version of code to calculate
factorial . Found this one
def fact(x):
return x > 1 and x * fact(x - 1) or 1
But I don't really get how ( x > 1 and x * fact(x - 1))
works .
