怎么利用python输出星座

def get_constellation(month, date):

    dates = (21, 20, 21, 21, 22, 22, 23, 24, 24, 24, 23, 22)

    constellations = ("摩羯", "水瓶", "双鱼", "白羊", "金牛", "双子", "巨蟹", "狮子", "处女", "天秤", "天蝎", "射手", "摩羯")

    if date < dates[month-1]:

    return constellations[month-1]

    else:

    return constellations[month]

print (get_constellation(7, 10) )
