python-股票数据定向爬取

Posted 2020-09-08

re.findall

soup.find_all

---------Q----

for i in ***:

***可以是什么类型，主要是关心什么类型的不可以

------------trackback用法------------

>>>
>>> import traceback
>>> try:
... 1/0
... except (Exception,e):
... traceback.print_exc()
...
Traceback (most recent call last):
File "<stdin>", line 2, in <module>
ZeroDivisionError: division by zero

During handling of the above exception, another exception occurred:

Traceback (most recent call last):
File "<stdin>", line 3, in <module>
NameError: name ‘e‘ is not defined

（说是这样报错更加直观
