• 用requests库和BeautifulSoup4库，爬取校园新闻列表的时间、标题、链接、来源。
• 选一个自己感兴趣的主题，做类似的操作，为“爬取网络数据并进行文本分析”做准备。

import requests
from bs4 import BeautifulSoup
net = \'http://news.gzcc.cn/html/xiaoyuanxinwen/\'
res = requests.get(net)
res.encoding=\'utf-8\'
doc = BeautifulSoup(res.text,\'html.parser\',from_encoding=\'utf-8\')
for news in doc.select(\'li\'):
    if len(news.select(\'.news-list-title\'))>0:
        title = news.select(\'.news-list-title\')[0].text
        url = news.select(\'a\')[0][\'href\']
        time = news.select(\'.news-list-info\')[0].contents[0].text
        main = news.select(\'.news-list-description\')[0].text
        source = news.select(\'.news-list-info\')[0].contents[1].text
        print(\'Url：{}\'.format(news.select(\'a\')[0][\'href\']))
        print(\'标题：{}\'.format(news.select(\'.news-list-title\')[0].text))
        print(\'正文：{}\'.format(news.select(\'.news-list-description\')[0].text))
        print(\'时间：{}\'.format(news.select(\'.news-list-info\')[0].contents[0].text))
        print(\'来源：{}\'.format(news.select(\'.news-list-info\')[0].contents[1].text))
