帮我用python写一个爬取城市天气信息的代码

好的，以下是Python的代码示例，使用BeautifulSoup和requests库：

import requests
from bs4 import BeautifulSoup

city = input("请输入要查询的城市名：")

def get_weather(city):
    url = "https://tianqi.moji.com/weather/china/" + city
    response = requests.get(url)
    soup = BeautifulSoup(response.text, "html.parser")
    temperature = soup.find("div", attrs={"class": "wea_weather clearfix"}).em.getText()
    weather = soup.find("div", attrs={"class": "wea_weather clearfix"}).b.getText()
    wind_direction = soup.find("div", attrs={"class": "wea_about clearfix"}).em.getText()
    wind_speed = soup.find("div", attrs={"class": "wea_about clearfix"}).i.getText()
    return temperature, weather, wind_direction, wind_speed

temperature, weather, wind_direction, wind_speed = get_weather(city)
print(f"{city}的天气信息：\n温度：{temperature}\n天气：{weather}\n风向：{wind_direction}\n风速：{wind_speed}")

希望以上代码能够帮到您，如果还有其他问题，可以随时再问我哦。
