Smile Need help with a python functuon      (list of str, dict
of {str: list of str}) -> list of str      The first parameter
is a list of movies that are currently in stock at a movie
store. The second parameter is a dictionary where each key is
the name of a customer and each value is a list of that
customer's favourite movies ordered from most to least
favourite. It is possible for a customer to have a favourite
movie that is not in stock at the store. Return a list of all
in-stock movies that are the first- or second-favourite movie of
at least one customer. The movies in the returned list must be
in the same order as in the first parameter and the returned
list must not contain duplicates. The parameters are not changed
by the function.   2. #2   3. Contributing User     Devshed
