用python输出星座

以下是一个简单的Python程序，可以根据输入的出生日期输出对应的星座：

month = int(input("请输入出生月份："))
day = int(input("请输入出生日期："))

if month == 1:
    if day <= 19:
        print("摩羯座")
    else:
        print("水瓶座")
elif month == 2:
    if day <= 18:
        print("水瓶座")
    else:
        print("双鱼座")
elif month == 3:
    if day <= 20:
        print("双鱼座")
    else:
        print("白羊座")
elif month == 4:
    if day <= 19:
        print("白羊座")
    else:
        print("金牛座")
elif month == 5:
    if day <= 20:
        print("金牛座")
    else:
        print("双子座")
elif month == 6:
    if day <= 21:
        print("双子座")
    else:
        print("巨蟹座")
elif month == 7:
    if day <= 22:
        print("巨蟹座")
    else:
        print("狮子座")
elif month == 8:
    if day <= 22:
        print("狮子座")
    else:
        print("处女座")
elif month == 9:
    if day <= 22:
        print("处女座")
    else:
        print("天秤座")
elif month == 10:
    if day <= 23:
        print("天秤座")
    else:
        print("天蝎座")
elif month == 11:
    if day <= 22:
        print("天蝎座")
    else:
        print("射手座")
elif month == 12:
    if day <= 21:
        print("射手座")
    else:
        print("摩羯座")
else:
    print("输入错误，请重新输入！")

该程序首先提示用户输入出生月份和日期，然后根据输入的值通过一系列的if-else语句判断对应的星座，并输出结果。
