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。

# -*- codding: utf-8 -*-

# -*- author: wf -*-
import requests
from bs4 import beautifulsoup
from datetime import datetime
url = ""
res = requests.get(url)
res.encoding = 'utf-8'
soup = beautifulsoup(res.text,'html.parser')
for news in soup.select('li'):
if len(news.select('.news-list-title'))>0 : #排除為空的li
data = news.select('.news-list-info')[0].contents[0].text #日期
title = news.select('.news-list-title')[0].text #標題
description = news.select('.news-list-description')[0].text #標題下的內容
a = news.select('a')[0].attrs['href'] #鏈結
'''print(data,title,description,a)'''
detail_res = requests.get(a)
detail_res.encoding = 'utf-8'
detail_soup = beautifulsoup(detail_res.text,'html.parser') #新聞詳情頁
content = detail_soup.select('#content')[0].text #正文內容
info = detail_soup.select('.show-info')[0].text #指令碼資訊
print(info)
break

3. 將其中的發布時間由str轉換成datetime型別。

#獲取當前時間

now_time = datetime.now()
now_time.year
exchangetime = datetime.strptime(publish_time,"%y-%m-%d %h:%m:%s") #字元轉換為時間
exchangestring = now_time.strftime('%y\%m\%d') #時間轉換為字元
4. 將完整的**及執行結果截圖發布在作業上。
