使用正则表达式，取得点击次数，函数抽离

1.用正则表达式判断邮箱是否输入正确

2.用正则表达式识别出全部的电话号码(这里用的是固话模式)

3.用正则表达式进行英文单词的分词

 

import re

Five score years ago, a great American, in whose symbolic shadow we stand today, signed the Emancipation Proclamation.
 This momentous decree came as a great beacon light of hope to millions of Negro slaves who had been seared in the
 flames of withering injustice. It came as a joyous daybreak to end the long night of bad captivity.

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):

from datetime import datetime

    clickRes = requests.get(clickUrl)
