1. 用正则表达式判定邮箱是否输入正确。
import re
r =‘^(\w)+(\.\w+)*@(\w)+((\.\w{2,3}){1,3})$‘
e =‘549571966@qq.com‘
if re.match(r,e):
print(re.match(r,e).group(0))
else:
print(‘error‘)
2. 用正则表达式识别出全部电话号码。

print(number)
3. 用正则表达式进行英文分词。re.split(‘‘,news)
import re news = ‘‘‘Failure is probably the fortification in your pole. It is like a peek your wallet as the thief, when you are thinking how to spend several hard-won lepta, when you are wondering whether new money, it has laid background.‘‘‘ word = re.split(‘[\s,.?\-]+‘,news) print(word)
4. 使用正则表达式取得新闻编号
import re newsUrl = ‘http://news.gzcc.cn/html/2017/xiaoyuanxinwen_095/8249.html‘ num=re.search(‘\_(.*).html‘,newsUrl).group(1) print(num)
5. 生成点击次数的Request URL
import re
newUrl = "http://news.gzcc.cn/html/2018/xiaoyuanxinwen_0404/9183.html"
newsId = re.findall("\_(.*).html",newUrl)[0].split("/")[-1];

res = requests.get(RequestUrl);
times=int(res.text.split(‘.html‘)[-1].lstrip("(‘)").rstrip("‘);"))
print(times)
7. 将456步骤定义成一个函数 def getClickCount(newsUrl):
import re
import requests
def getClickCount(newsUrl):

RequestUrl = "http://oa.gzcc.cn/api.php?op=count&id={}&modelid=80".format(newsId)
res = requests.get(RequestUrl);
times=int(res.text.split(‘.html‘)[-1].lstrip("(‘)").rstrip("‘);"))
return times
time=getClickCount("http://news.gzcc.cn/html/2018/xiaoyuanxinwen_0404/9183.html")
print(time)
8. 将获取新闻详情的代码定义成一个函数 def getNewDetail(newsUrl):
import requests
from bs4 import BeautifulSoup
def getNewDetail(newsUrl):
res = requests.get(newsUrl)
res.encoding = ‘utf-8‘
soup = BeautifulSoup(res.text, ‘html.parser‘)
print(soup.select("#content")[0].text) # 正文
info = soup.select(".show-info")[0].text
time = info.lstrip(‘发布时间:‘)[:19]
# 作者
if info.find(‘作者:‘) > 0:
author = info[info.find(‘作者:‘):info.find(‘审核:‘)].lstrip(‘作者:‘).split()[0]
else:
author = ‘none‘;
print(author)
getNewDetail(‘http://news.gzcc.cn/html/2018/xiaoyuanxinwen_0404/9183.html‘)
9. 取出一个新闻列表页的全部新闻 包装成函数def getListPage(pageUrl):
import re
import requests
from bs4 import BeautifulSoup
def getListPage(pageUrl):
res = requests.get(pageUrl)
res.encoding = ‘utf-8‘
soup = BeautifulSoup(res.text, ‘html.parser‘)

import re
import requests
from bs4 import BeautifulSoup
#获取点击次数
def getClickCount(newsUrl):
newsId = re.findall("\_(.*).html",newsUrl)[0].split("/")[-1];
RequestUrl = "http://oa.gzcc.cn/api.php?op=count&id={}&modelid=80".format(newsId)
res = requests.get(RequestUrl);
times=int(res.text.split(‘.html‘)[-1].lstrip("(‘)").rstrip("‘);"))
return times
#获取新闻详细信息
def getNewDetail(newsUrl):
res = requests.get(newsUrl)
res.encoding = ‘utf-8‘
soup = BeautifulSoup(res.text, ‘html.parser‘)
# print(soup.select("#content")[0].text) # 正文
info = soup.select(".show-info")[0].text
time = info.lstrip(‘发布时间:‘)[:19]
# 作者
if info.find(‘作者:‘) > 0:
author = info[info.find(‘作者:‘):info.find(‘审核:‘)].lstrip(‘作者:‘).split()[0]
else:
author= ‘none‘;
print("作者:"+author+" "+"发布时间"+time)
#获取该页新闻的信息
def getListPage(pageUrl):
res = requests.get(pageUrl)
res.encoding = ‘utf-8‘
soup = BeautifulSoup(res.text, ‘html.parser‘)
for news in soup.select("li"):
if len(news.select(".news-list-title")) > 0:
time = news.select(".news-list-info")[0].contents[0].text
title = news.select(".news-list-title")[0].text
description = news.select(".news-list-description")[0].text
url = news.select(‘a‘)[0].attrs[‘href‘]
print(time+" "+title+" "+description+" "+url)
a=getClickCount(url);
print("点击"+str(a)+"次")
getNewDetail(url)
#获取页数
def getPageN():
res = requests.get(‘http://news.gzcc.cn/html/xiaoyuanxinwen/‘)
res.encoding = "utf-8"
soup = BeautifulSoup(res.text, ‘html.parser‘)
n = int(soup.select(‘#pages‘)[0].select(‘a‘)[0].text.rstrip(‘条‘))
return (n // 10 + 1)
n=getPageN();
for i in range(1,n+1):
if(i==1):
