I was moving on to this lesson and I did the code it asked me to do:
def is_even(x): if x % 2: return True else: return False
I ran the code and it kept giving me an error like this: is_even(38) returned False instead of True, so I flip-flopped the True and the False:
def is_even(x): if x % 2: return False else: return True
And it worked...
