beautifulsoup "list对象没有属性"错误
我正在尝试从一个天气网站上抓取温度数据,使用的代码如下:
import urllib2
from BeautifulSoup import BeautifulSoup
f = open('airport_temp.tsv', 'w')
f.write("Location" + "\t" + "High Temp (F)" + "\t" + "Low Temp (F)" + "\t" + "Mean Humidity" + "\n" )
eventually parse from http://www.wunderground.com/history/airport/\w{4}/2012/\d{2}/1/DailyHistory.html
for x in range(10):
locationstamp = "Location " + str(x)
print "Getting data for " + locationstamp
url = 'http://www.wunderground.com/history/airport/KAPA/2013/3/1/DailyHistory.html'
page = urllib2.urlopen(url)
soup = BeautifulSoup(page)
location = soup.findAll('h1').text
locsent = location.split()
loc = str(locsent[3,6])
hightemp = soup.findAll('nobr')[6].text
htemp = hightemp.split()
ht = str(htemp[1])
lowtemp = soup.findAll('nobr')[10].text
ltemp = lowtemp.split()
lt = str(ltemp[1])
avghum = soup.findAll('td')[23].text
f.write(loc + "\t|" + ht + "\t|" + lt + "\t|" + avghum + "\n" )
f.close()
但是,我遇到了一个错误,提示是:
Getting data for Location 0
Traceback (most recent call last):
File "airportweather.py", line 18, in <module>
location = soup.findAll('H1').text
AttributeError: 'list' object has no attribute 'text'
我查阅了Beautiful Soup和Python的文档,但我还是比较菜,所以没能搞明白。请帮帮我这个新手!

这很简单。findAll
会返回一个列表,所以如果你确定你只对一个特定的元素感兴趣,那么可以这样写:soup.findAll('H1')[0].text
这样就可以得到你想要的内容了。

.findAll()
方法会返回一个匹配结果的 列表。如果你只想要 一个 结果,可以使用 .find()
方法。或者,你也可以像其他代码那样选择一个特定的元素,或者遍历所有的结果:
location = soup.find('h1').text
或者
locations = [el.text for el in soup.findAll('h1')]
或者
location = soup.findAll('h1')[2].text
