爬取校园新闻首页的新闻

1. 用requests库和BeautifulSoup库，爬取校园新闻首页新闻的标题、链接、正文。

import requests
from bs4 import BeautifulSoup

url = 'http://news.gzcc.cn/html/xiaoyuanxinwen/'
res = requests.get(url)
res.encoding = 'utf-8'
soup = BeautifulSoup(res.text, 'html.parser')

news = soup.select('li')
for new in news:
    if len(new.select('.news-list-title')) > 0:
        title = new.select('.news-list-title')[0].text
        href = new.select('a')[0].attrs['href']
        text = new.select('.news-list-description')[0].text
        print(title)
        print(href)
        print(text+'
')

2. 分析字符串，获取每篇新闻的发布时间，作者，来源，摄影等信息。

import requests
from bs4 import BeautifulSoup

url = 'http://news.gzcc.cn/html/xiaoyuanxinwen/'
res = requests.get(url)
res.encoding = 'utf-8'
soup = BeautifulSoup(res.text, 'html.parser')

news = soup.select('li')
for new in news:
    if len(new.select('.news-list-title')) > 0:
        title = new.select('.news-list-title')[0].text
        href = new.select('a')[0].attrs['href']
        text = new.select('.news-list-description')[0].text
        res = requests.get(href)
        res.encoding = 'utf-8'
        soup = BeautifulSoup(res.text, 'html.parser')
        info = soup.select('.show-info')[0].text
        content = info.split()
        time = content[0].lstrip('发布时间:') + " " + content[1]
        author = content[2].lstrip('作者：')
        check = content[3].lstrip('审核：')
        source = content[4].lstrip("来源：")
        print(time, author, check, source)

3. 将其中的发布时间由str转换成datetime类型。

from datetime import datetime
time = '2018-04-04 05:20:34'
a = datetime.strptime(time, '%Y-%m-%d %H:%M:%S')
print(type(a))
print(a, a.strftime('%Y/%m/%d'))

4. 将完整的代码及运行结果截图发布在作业上。
