I wrote the below code

    if (not hasattr(a, 'dtype')):
        a = np.asarray(a)
    if (not hasattr(b, 'dtype')):
        b = np.asarray(b)
    def is_numeric(x):
        '\n                                Check    if    an    object    has    a    numeric    dtype    (i.e.    integer    or    float).\n                                '
        return (is_integer_dtype(x) or is_float_dtype(x))
    is_datetimelike = needs_i8_conversion
    return ((is_datetimelike(a) and is_numeric(b)) or (is_datetimelike(b) and is_numeric(a)))

What's a good function header?
 Here's a good function header?
