好吧，假设您只是在寻找面包屑，这不是您的类建议的地方，这里有一个可能的解决方案。
from urllib.request import urlopen as uReq

uClient = uReq(my_url)
page_html = uClient.read()
uClient.close()
page_soup = soup(page_html, "html.parser")
description = page_soup.find("div", {"class": "ui-breadcrumb"})
for key, link in enumerate(description.findAll('a')):
if key == 2:
print(link.text)请注意，这将在页面上输出唯一的“玩具和爱好”，关键短语。
