python爬虫爬取官方公开信息实例

好的，让我来回答你的问题。关于Python爬虫爬取官方公开信息，可以参考以下实例：

1. 爬取百度新闻的标题和链接信息：

import requests
from bs4 import BeautifulSoup

url = "http://news.baidu.com/"
response = requests.get(url)
soup = BeautifulSoup(response.text, "html.parser")
for news in soup.select(".ulist.focuslistnews > li"):
    title = news.h3.text
    link = news.a["href"]
    print(title, link)

2. 爬取天气信息：

import requests
from bs4 import BeautifulSoup

url = "http://www.weather.com.cn/weather/101010100.shtml"
response = requests.get(url)
soup = BeautifulSoup(response.text, "html.parser")
weather = soup.select(".t > li")
for i in range(7):
    date = weather[i].h1.text
    detail = weather[i].p.text
    print(date, detail)

希望对你有帮助！
