输⼊⼀个⽣⽇⽇期输出其星座 ⽩⽺座321-419⾦⽜座420-520双⼦座521-621巨蟹座622-722 狮⼦座723-822处⼥座823-922天秤座923-1023天蝎座1024-1122 射⼿座1123-1221魔羯座1222-119⽔瓶座120-218双⻥座219-320

实现思路：

1. 接收用户输入的生日日期；
2. 根据生日日期中的月份和日期，判断出该生日日期属于哪个星座；
3. 输出该生日日期对应的星座。

参考代码如下：

birthday = input("请输入生日日期(格式：MM/DD): ")
month = int(birthday.split("/")[0])  # 获取生日日期中的月份
day = int(birthday.split("/")[1])    # 获取生日日期中的日份

# 判断星座
if (month == 3 and day >= 21) or (month == 4 and day <= 19):
    constellation = "白羊座"
elif (month == 4 and day >= 20) or (month == 5 and day <= 20):
    constellation = "金牛座"
elif (month == 5 and day >= 21) or (month == 6 and day <= 21):
    constellation = "双子座"
elif (month == 6 and day >= 22) or (month == 7 and day <= 22):
    constellation = "巨蟹座"
elif (month == 7 and day >= 23) or (month == 8 and day <= 22):
    constellation = "狮子座"
elif (month == 8 and day >= 23) or (month == 9 and day <= 22):
    constellation = "处女座"
elif (month == 9 and day >= 23) or (month == 10 and day <= 23):
    constellation = "天秤座"
elif (month == 10 and day >= 24) or (month == 11 and day <= 22):
    constellation = "天蝎座"
elif (month == 11 and day >= 23) or (month == 12 and day <= 21):
    constellation = "射手座"
elif (month == 12 and day >= 22) or (month == 1 and day <= 19):
    constellation = "魔羯座"
elif (month == 1 and day >= 20) or (month == 2 and day <= 18):
    constellation = "水瓶座"
else:
    constellation = "双鱼座"

print("您的星座是：" + constellation)

运行结果如下：

请输入生日日期(格式：MM/DD): 10/25
您的星座是：天蝎座
