python - 美丽的汤得到标签或得到价格

Answer 1

在以下代码中：

foundPrice = soup.findAll('span', {'itemprop':'price'})
if found is not None:

您将结果分配给findAllto foundPrice，但if语句 compare found。

尝试以下操作：

import urllib2

from bs4 import BeautifulSoup


url = 'http://www.fastfurnishings.com/Aura-Floor-Lamp-p/lsi_ls-aurafl-gy-gn.htm'
u = urllib2.urlopen(url)
try:
    soup = BeautifulSoup(u)
finally:
    u.close()

span = soup.find('span', {'itemprop':'price'})
if span is not None:
    print span.string
else:
    print 'Not found'
