解决方案
Easy with BeautifulSoup :)
<预><代码>>>>从 bs4 导入 BeautifulSoup>>>汤 = BeautifulSoup('<option value="BC">BRITISH COLUMBIA</option>')>>>汤.find('option')['selected'] = ''>>>打印汤<html><body><option selected="" value="BC">不列颠哥伦比亚省</option></body></html>属性可以看作是一本字典.所以我们有 {'value':'BC'}，并且要向字典添加一个值，我们只需执行 dict[key] = value
Question for you here, I'm trying to add an attribute to a tag here, wondering if I can use a BeautifulSoup method, or should use plain string manipulation.
An example would probably make this clear, as it's a weird explanation.
How the HTML Code looks now:
<option value="BC">BRITISH COLUMBIA</option>
How I would like it to look:
<option selected="" value="BC">BRITISH COLUMBIA</option>
Thanks for the help!

Easy with BeautifulSoup :)
>>> from bs4 import BeautifulSoup
>>> soup = BeautifulSoup('<option value="BC">BRITISH COLUMBIA</option>')
>>> soup.find('option')['selected'] = ''
>>> print soup
<html><body><option selected="" value="BC">BRITISH COLUMBIA</option></body></html>
The attributes can be looked at as a dictionary. So we have {'value':'BC'}, and to add a value to a dictionary, we just do dict[key] = value
