需要导入上一节的结果city10.py
#!/usr/bin/python
# -*- coding: UTF-8 -*-
import urllib.request
from city10 import city #从city10.py里导入city变量名称
import json #json包,loads的用法
import traceback
cityname=input(‘你想查询什么城市的天气?\n‘)
citycode=city.get(cityname) # citycode=city[cityname]
#print (citycode)
#print (cityname)

web=‘http://www.weather.com.cn/data/cityinfo/%s.html‘ %citycode
content=urllib.request.urlopen(web).read().decode()
data=json.loads(content)
#print (data)
print(type(content))
print(type(data))
result=data[‘weatherinfo‘] #获取weatherinfo键的值为{‘cityid‘:‘101010100‘}
# 就好比result={}
a=(‘%s\n%s~%s‘)%(result[‘weather‘], result[‘temp1‘], result[‘temp2‘])
print(a)
except Exception as e:
#traceback.print_exc()
print(Exception,":",e)
print(‘查询失败‘)
