from datetime import datetime, timedelta
import threading
import requests
import json
import re

通常會分段，變成：

from datetime import datetime, timedelta

import threading
import requests
import json
import re

[linroex]

topic  =  self.topic,  
author  =  self.author,  
datetime  =  self.datetime,

程式碼分段...

if __name__ == '__main__':
    target = myspider.Spider('https://tw.news.yahoo.com/')
    target.add_channel('https://tw.news.yahoo.com/society/')
    target.add_channel('https://tw.news.yahoo.com/finance/')
    target.add_channel('https://tw.news.yahoo.com/art-edu/')
    target.start()

分段後：

if __name__ == '__main__':
    target = myspider.Spider('https://tw.news.yahoo.com/')

    target.add_channel('https://tw.news.yahoo.com/society/')
    target.add_channel('https://tw.news.yahoo.com/finance/')
    target.add_channel('https://tw.news.yahoo.com/art-edu/')

    target.start()
