#Lazy Python programmer def fact(x): return x > 1 and x * fact(x  1) or 1 print fact(6)

#Python hacker import sys @tailcall def fact(x, acc=1): if x: return fact(x.__sub__(1), acc.__mul__(x)) return acc sys.stdout.write(str(fact(6)) + '\n')
#EXPERT PROGRAMMER import c_math fact = c_math.fact print fact(6)
