Here's a good function header given the following:
I wrote the below code

    def f1(object, a, b, c):
        'Docstring    for    f1\n\n                                Parameters\n                                ----------\n                                object    :    object\n                                                Some    object.    This    description    also    has\n\n                                                blank    lines    in    it.\n                                a    :    int\n                                                Parameter    a\n                                b    :    int\n                                                Parameter    b\n                                '
