使用正则表达式，取得点击次数，函数抽离-优快云博客

本文介绍了如何利用正则表达式实现多种实用功能，包括验证电子邮件格式、提取电话号码、进行英文文本分词等，并提供了具体的Python代码示例。

学会使用正则表达式

1. 用正则表达式判定邮箱是否输入正确。

2. 用正则表达式识别出全部电话号码。

3. 用正则表达式进行英文分词。re.split('',news)

4. 使用正则表达式取得新闻编号

5. 生成点击次数的Request URL

6. 获取点击次数

7. 将456步骤定义成一个函数 def getClickCount(newsUrl):

8. 将获取新闻详情的代码定义成一个函数 def getNewDetail(newsUrl):

import requests
import re

newsUrl = 'http://news.gzcc.cn/html/2017/xiaoyuanxinwen_0925/8249.html'

def getClickCount(newsUrl):
    newsId = re.search('\_(.*).html', newsUrl).group(1).split('/')[-1]
    res = requests.get('http://oa.gzcc.cn/api.php?op=count&id={}&modelid=80'.format(newsId))
    return (int(res.text.split('.html')[-1].lstrip("(')").rstrip("');")))


click = getClickCount(newsUrl)
print(click)

r = '^(\w)+(\.\w+)*@(\w)+(\w)+((\.\w{2,3}){1,3})$'
e = '3947653@qq.com'
if re.match(r, e):
    print(re.match(r, e).group(0))
else:
    print('error')

tel = re.findall('(\d{3,4})-(\d{6,8})', str)
print(tel)

Finally, however, his friend persuaded him that it was very safe, and Mr. Johnson boarded the plane.'''
word = re.split('[\s,.?\-]+', news)
print(word)

re.search('\_(.*).html',newsUrl).group(1)
re.findall('',newsUrl)
