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

你可以使用Python编写一个基于Streamlit的星座计算器。下面是一个示例代码：

import streamlit as st

def calculate_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 <= 21):
        return "双子座"
    elif (month == 6 and day >= 22) 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 <= 23):
        return "天秤座"
    elif (month == 10 and day >= 24) or (month == 11 and day <= 22):
        return "天蝎座"
    elif (month == 11 and day >= 23) or (month == 12 and day <= 21):
        return "射手座"
    else:
        return "摩羯座"

def main():
    st.title("星座计算器")
    st.write("请输入您的出生年月日：")
    
    day = st.number_input("日", min_value=1, max_value=31)
    month = st.number_input("月", min_value=1, max_value=12)
    year = st.number_input("年", min_value=1900, max_value=2022)
    
    if st.button("计算"):
        zodiac_sign = calculate_zodiac_sign(day, month)
        st.write("您的星座是：" + zodiac_sign)

if __name__ == "__main__":
    main()

你可以将上述代码保存到一个Python文件中（例如zodiac_calculator.py），然后在终端中运行以下命令启动Streamlit应用程序：

streamlit run zodiac_calculator.py

这将在浏览器中打开一个页面，你可以在页面上输入出生年月日，并点击“计算”按钮来获取对应的星座。
