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

    n_named_inputs = len(named_inputs)
    def get_plural(n):
        if (n > 1):
            return 's'
        else:
            return ''
    if (n_named_inputs == 0):
        if (n_unnamed_inputs == 0):
            msg = 'The    function    is    supposed    to    have    no    input.'
        elif (n_unnamed_inputs == 1):
            msg = "The    function    has    a    single    input    variable    which    has    no    name,    and    thus    cannot    be    assigned    through    a    keyword    argument    (use    'name=...'    in    a    Variable's    constructor    to    give    it    a    name)."
        else:
            msg = ("The    function    has    %s    inputs,    but    none    of    them    is    named,    and    thus    they    cannot    be    assigned    through    keyword    arguments    (use    'name=...'    in    a    Variable's    constructor    to    give    it    a    name)." % n_unnamed_inputs)
    elif (n_unnamed_inputs == 0):
        msg = ('The    function    has    %s    named    input%s    (%s).' % (n_named_inputs, get_plural(n_named_inputs), ',    '.join(named_inputs)))
    else:
        msg = ("The    function    has    %s    named    input%s    (%s),    and    %s    unnamed    input%s    which    thus    cannot    be    accessed    through    keyword    argument%s    (use    'name=...'    in    a    variable's    constructor    to    give    it    a    name)." % (n_named_inputs, get_plural(n_named_inputs), ',    '.join(named_inputs), n_unnamed_inputs, get_plural(n_unnamed_inputs), get_plural(n_unnamed_inputs)))
    return msg

What's a good function header?
