There's nothing wrong with constructing the dictionary like this, but you can  save yourself a few keystrokes by instantiating the dictionary with key/value pairs:

    donors = {
        u"John Doe": [1010.75, 537.25, 5300],
        u"Jane Doe": [1234],
        ...
        u"Marie Curie": [1000, 3200.50]
    }
