python - 美丽的汤教程错误：jeriwieringa.com

Question

我从这里的教程（http://jeriwieringa.com/blog/2012/11/04/beautiful-soup-tutorial-part-1/）运行此代码：

from bs4 import BeautifulSoup

soup = BeautifulSoup (open("43rd-congress.htm"))

final_link = soup.p.a
final_link.decompose()

links = soup.find_all('a')
for link in links:
names = link.contents[0]
fullLink = link.get('href')
print names
print fullLink

我得到这个错误：

File "soupexample.py", line 11, in <module>
fullLink = link.get('href')
link is not defined

为什么我需要在此循环的链接中定义链接？逻辑是什么？谢谢你的帮助。

Answer 1

我想错误来自这里（不知何故，示例中没有缩进，当然应该有）：

for link in links:
    names = link.contents[0]
    fullLink = link.get('href')
    print names
    print fullLink
