爬取重庆近半个月天气python代码

对于爬取重庆近半个月天气的Python代码，可以使用requests库来进行网络请求，然后解析返回的HTML页面获取所需的天气数据。以下是一个示例代码：

import requests
from bs4 import BeautifulSoup

def get_weather(city):
    url = f'http://www.weather.com.cn/weather15d/{city}.shtml'
    headers = {
        'User-Agent': 'Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/91.0.4472.124 Safari/537.36'
    }
    response = requests.get(url, headers=headers)
    response.encoding = 'utf-8'
    soup = BeautifulSoup(response.text, 'html.parser')
    weather_data = soup.find(class_='t clearfix').find_all('li')

    weather_info = []
    for item in weather_data:
        date = item.find(class_='date').text
        weather = item.find(class_='wea').text
        temperature = item.find(class_='tem').text
        weather_info.append({'date': date, 'weather': weather, 'temperature': temperature})

    return weather_info

city = '重庆'
weather_info = get_weather(city)
for info in weather_info:
    print(f"日期：{info['date']}，天气：{info['weather']}，温度：{info['temperature']}")
