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

    if (physical_line.find('N401:    def    foo()') != (-1)):
        return
    if is_docstring(physical_line, previous_logical):
        pos = max([physical_line.find(i) for i in START_DOCSTRING_TRIPLE])
        if (physical_line[(pos + 3)] == '    '):
            return (pos, 'N401:    docstring    should    not    start    with    a    space')

What's a good function header?
