beautifulsoup「列表對象有沒有屬性」的錯誤

Question

我想用下面刮從weather site溫度：

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() 

不幸的是，我得到一個錯誤說：

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' 

我通過BS和Python文檔查看，但我仍然很綠，所以我無法弄清楚。請幫助這個新手！

Answer 1

這很簡單。 findAll返回列表，所以如果你確信只有一個有意思嗎元素，則：soup.findAll('H1')[0].text應該工作

Answer 2

的.findAll()方法返回匹配的列表。如果您想要一個結果，請改用.find()方法。另外，挑選出一個特定的元素，如代碼執行，或循環的其餘部分在結果：

location = soup.find('h1').text 

或

locations = [el.text for el in soup.findAll('h1')] 

或

location = soup.findAll('h1')[2].text
