我正在尝试使用以下代码从气象网站中抓取温度数据:
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()
很遗憾,我收到了一个错误提示:
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'
我已查看了BS和Python文档,但仍然很生疏,因此无法理解。请帮助这个新手!
