通过streamlit编写页面实现一个星座计算器。 即：输入出生年月日可以输出对应的星座完善一下

下面是一个使用Streamlit编写的星座计算器的示例代码：

import streamlit as st

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

st.title("星座计算器")

day = st.number_input("出生日期", min_value=1, max_value=31)
month = st.number_input("出生月份", min_value=1, max_value=12)

if st.button("计算"):
    zodiac_sign = get_zodiac_sign(day, month)
    st.write("您的星座是:", zodiac_sign)

你可以将上面的代码保存到一个名为app.py的文件中，并在命令行中运行streamlit run app.py来启动应用程序。然后，你将能够在浏览器中访问该应用程序，并使用日期选择器来输入出生日期和月份，然后点击"计算"按钮来获取相应的星座。输出结果将会在页面上显示出来。
