在這個page，我試圖刮，我想排除那些有屬性的<td>。查找標籤，除了那些屬性：BeautifulSoup
<td >點擊此處查看阿根廷</td>一個全面的區域代碼列表
我想知道用什麼功能/ s到排除與屬性
這個標籤我的代碼獲取所有城市和地區代碼
from bs4 import BeautifulSoup
import urllib2
import re
url = "http://www.howtocallabroad.com/argentina"
html_page = urllib2.urlopen(url)
soup = BeautifulSoup(html_page)
areatable = soup.find('table',{'id':'codes'})
if areatable is None:
print "areatable is None"
else:
d = {}
def chunks(l, n):
return [l[i : i + n] for i in range(0, len(l), n)]
all_td = areatable.findAll('td')
print all_td
li = dict(chunks([i.text for i in all_td], 2))
print li
但是，當我嘗試打印li，它拋出一個異常：
Traceback (most recent call last):
File "extract_table.py", line 21, in <module>
li = dict(chunks([i.text for i in all_td], 2))
ValueError: dictionary update sequence element #30 has length 1; 2 is required
這就是我得到我的呼喚areatable.findAll('td')
