#task 9. Write a function that takes a list of dictionaries (each has "name" and "score") and returns the name of the person with the highest score.

'''def myfunc(val: list):

#task 10. Write a function that takes two lists — one of keys, one of values — and combines them into a dictionary.

    res = dict(zip(val1, val2))
    return res

res = combiner(["alice", "jane", "mary"], [15, 16, 17])
