Recursive Positive Number Check

>>> def isPositive(number): try: if(number - 1 == 0): return True else: return isPositive(number - 1) except: return False >>> isPositive(30) True >>> isPositive(0) False >>> isPositive(-100) False >>> isPositive(100) True

A Python REPL shows a recursively defined function checking whether a number is positive. The joke is that the function works for positive inputs by counting down recursively, but incorrectly returns false for zero and negative values, presenting flawed code as a cringe programming example.
