求教：Python列表索引超出范围

import urllib2
import json

url1 = ('http://m.weather.com.cn/data5/city.xml' )
content1 = urllib2.urlopen(url1).read()
provinces = content1.split(',')

result = 'city = {\n'
url = 'http://m.weather.com.cn/data3/city%s.xml'
for p in provinces:
p_code = p.split('|')[0]
url2 = url % p_code
content2 = urllib2.urlopen(url2).read()
cities = content2.split(',')


for c in cities:
c_code = c.split('|')[0]
url3 = url % c_code
content3 = urllib2.urlopen(url3).read()
districts = content3.split(',')


for d in districts:
d_pair = d.split('|')
d_code = d_pair[0]
name = d_pair[1]
url4 = url % d_code
content4 = urllib2.urlopen(url4).read()
code = content4.split('|')[1]
line = " '%s': '%s',\n" %(name,code)
result += line
print name + ':' + code
result += '}'
f = file('F:\untitled\citys.py','w')
f.write(result)
f.close()

出现下面的错误：
Traceback (most recent call last):
File "F:/untitled/1.py", line 32, in <module>
code = content4.split('|')[1]
IndexError: list index out of range

code = content4.split('|')[1] 很明显，split后，某些时候，它没有第二个数据，所以就报错了

这个我还是没怎么听明白，我是刚学的，能不能说的通俗点啊，还有这是咋改的

引用 2 楼 Jschao 的回复:

主要就是加个try，会报错的让它pass就行了
