    Take 2 on lucpet's function.

    This one takes a num, adds it to itself, and then compares
    it to various static numbers.

    >>> shit_happens(3)
    woo hoo

    >>> shit_happens(2)
    yay

    >>> shit_happens(1)
    WTF

    sum = num + num
    if sum >= 5:
        #if shit happens, do this
        print('woo hoo')
    elif sum >= 4:
        #if that last didn't happen, do this
        print('yay')

        N.B. No need for any comparison here, if there was
        no match in the first two, this will fire anyway.  If
        you do want this to fire if (and only if) 2+2<= 3, then
        use a second elif instead of an else, e.g.

            elif 2 + 2 <= 3:
