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

    def mpl_execfile(fname, *where, **kw):
        'matplotlib-aware    wrapper    around    safe_execfile.\n\n                                Its    interface    is    identical    to    that    of    the    :func:`execfile`    builtin.\n\n                                This    is    ultimately    a    call    to    execfile(),    but    wrapped    in    safeties    to\n                                properly    handle    interactive    rendering.'
        import matplotlib
        import matplotlib.pyplot as plt
        is_interactive = matplotlib.rcParams['interactive']
        matplotlib.interactive(False)
        safe_execfile(fname, *where, **kw)
        matplotlib.interactive(is_interactive)
        if plt.draw_if_interactive.called:
            plt.draw()
            plt.draw_if_interactive.called = False
        try:
            da = plt.draw_all
        except AttributeError:
            pass
        else:
            da()
    return mpl_execfile

What's a good function header?
