爬取校園新聞首頁的新聞

1. 用requests庫和beautifulsoup庫，爬取校園新聞首頁新聞的標題、鏈結、正文。

import requests

from bs4 import beautifulsoup
res = requests.get('')
res.encoding = 'utf-8'
soup = beautifulsoup(res.text,'html.parser')
for news in soup.select('li'):
if len(news.select('.news-list-title'))>0:
d = news.select('.news-list-info')[0].contents[0].text #時間
t = news.select('.news-list-title')[0].text #標題
a = news.select('a')[0].attrs['href'] #url
print(d, t, a)

2. 分析字串，獲取每篇新聞的發布時間，作者，**，攝影等資訊。

res2 = requests.get(a)

res2.encoding = 'utf-8'
soup2 = beautifulsoup(res2.text,'html.parser')
x = soup2.select('.show-content')[0].text
info = soup2.select('.show-info')[0].text.split()
# print(soup2.select('#content')[0].text)
print(s,zz,sh,ly)

3. 將其中的發布時間由str轉換成datetime型別。

from datetime import datetime

time = '2018-04-01 11:57:00'
a = datetime.strptime(time, '%y-%m-%d %h:%m:%s')
print(type(a))
print(a, a.strftime('%y/%m/%d'))

4. 將完整的**及執行結果截圖發布在作業上

import requests

from bs4 import beautifulsoup
from datetime import datetime
res = requests.get('')
res.encoding = 'utf-8'
soup = beautifulsoup(res.text,'html.parser')
for news in soup.select('li'):
if len(news.select('.news-list-title'))>0:
d = news.select('.news-list-info')[0].contents[0].text #時間
t = news.select('.news-list-title')[0].text #標題
a = news.select('a')[0].attrs['href'] #url
print(d,t,a)
res2 = requests.get(a)
res2.encoding = 'utf-8'
soup2 = beautifulsoup(res2.text,'html.parser')
x = soup2.select('.show-content')[0].text
info = soup2.select('.show-info')[0].text.split()
# print(soup2.select('#content')[0].text)
cc = datetime.strptime(s, '%y-%m-%d %h:%m:%s')
print(cc,type(cc))
print(cc.strftime('%y/%m/%d'),zz,sh,ly)
