python获取接口数据，写入文件

import types
import urllib2
import json

duan ="--------------------------"  #在控制台断行区别的

###利用urllib2获取网络数据
def registerUrl():
try:
url ="http://m.weather.com.cn/data/101010100.html"
data = urllib2.urlopen(url).read()
return data
except Exception,e:
print e

###写入文件
def jsonFile(fileData):
file = open("d:\json.txt","w")
file.write(fileData)
file.close()

###解析从网络上获取的JSON数据
def praserJsonFile(jsonData):
value = json.loads(jsonData)
rootlist = value.keys()
print rootlist
print duan
for rootkey in rootlist:
print rootkey
print duan
subvalue = value[rootkey]
print subvalue
print duan
for subkey in subvalue:
print subkey,subvalue[subkey]

if ____name____ == "____main____":
# xinput = raw_input()
# x = 130
# xvalue = cmp(x,xinput)
# print xvalue
# print x/100.0

data = registerUrl()
# jsonFile(data)

praserJsonFile(data)
