Language/Type: Python collections dict

Write the dictionary returned when the following function is passed each of the following lists.

def mystery(numbers):
    data = {}
    for el in numbers:
        if el in data:
            data[el].append(1)
        else:
            data[el] = []
    return data

Though dictionaries store their contents in unpredictable order, for this problem, write the pairs sorted by alphabetical ordering of the keys. Write your answer in this format: {key: value, key: value}

`[1, 2, 34, 3, 4, 1, 2, 4, 2, 14]`
`[1, 1, 1, 2, 2, 2, 1, 4, 4, 4]`
`[45, 43, 44, 54, 45, 45, 54, 43]`
