第三步 尝试编写代码，反复测试
[Python] 纯文本查看 复制代码import requests
import json
import re
import time
from lxml import etree
if __name__ == '__main__':
url = 'https://www.cls.cn/api/sw?app=CailianpressWeb&os=web&sv=7.7.5&sign=bf0f367462d8cd70917ba5eab3853bce'

data = {"type":"telegram","keyword":"你需要知道的隔夜全球要闻","page":0,"rn":20,"os":"web","sv":"7.7.5","app":"CailianpressWeb"}
response = requests.post(url=url,headers=headers,data=data)
news = json.loads(response.text)['data']['telegram']['data'][0]['descr']
timeStamp = json.loads(response.text)['data']['telegram']['data'][0]['time']
timeArray = time.localtime(timeStamp)
formatTime = time.strftime("%Y年%m月%d日", timeArray)
news = re.split(r'\d+、',news)
title = ''.join(etree.HTML(news[0]).xpath('//text()'))[1:-2]
print(formatTime,title)
for i in range(1, len(news)):
new = '%s、%s'%(i,news)
print(new)

存在问题，本想通过正则表达式在"。数字、"数字前面通过正则替换内容替换新增换行，没想到输出的时候数字被\d+替换了。
感谢大神@Arcticlyc指点，优化正则替换。
如有不足，欢迎大家提出意见。
