python 爬虫刚开始学习的一个问题

Question

这段代码，当我点Execute Selection in Console时候，可以正常运行，并且结果和教材一致

但是我直接运行这个文件时，就开始报错了

这是怎么回事呢？？
错误信息如下：
C:\Users\yzy\AppData\Local\Programs\Python\Python36\python.exe C:/Users/yzy/Desktop/python/webscraping.py
Traceback (most recent call last):
File "C:\Users\yzy\AppData\Local\Programs\Python\Python36\lib\bz2.py", line 19, in
from threading import RLock
ImportError: cannot import name 'RLock'

During handling of the above exception, another exception occurred:

Traceback (most recent call last):

你自己建的py文件起名字不要和python的包名一样！问题应该出在这里，你自己写的threading.py文件把python的threading覆盖了
