(1)程序查询结果图(图中较下的图是百度查询天气的结果)
(2)http://developer.baidu.com/map/carapi-7.htm 百度车联网接口说明中有天气查询的接口，目前是免费提供的(一天可以查询5000次)
下表是接口返回的json数据。(表中##及后内容是为了方便的查看数据填写的)

import urllib.parse
url0 = 'http://api.map.baidu.com/telematics/v3/weather'
url ='http://api.map.baidu.com/telematics/v3/weather?location=北京&output=json&ak=yourkey'
url1 ='https://www.python.org/'
###最简单的方式
##response = urllib.request.urlopen(url1)
##buff = response.read()
##html = buff.decode('utf8')
##response.close()#记得关闭
##print(html)
###使用Request的方式，这种方式同样可以用来处理其他URL，例如FTP：
##import urllib.request
##req = urllib.request.Request(url1)
##response = urllib.request.urlopen(req)
##buff = response.read()
###显示
##the_page = buff.decode('utf8')
##response.close()
##print(the_page)
#使用GET请求
#例子中用到百度车联网中提供的天气查询api接口：

#http://api.map.baidu.com/telematics/v3/weather?location=北京&output=json&ak=yourkey
#decode('gb2312')
name1=input('请输入城市:')
#url1 = 'http://api.map.baidu.com/telematics/v3/weather?location='+name1+'&output=json&ak=yourkey'
#print(url1)
data = {'location':name1,
'output':'json',
'ak':'RehcDwqFhr77yNTZVGKPA45U'}#ak后面的值是我在百度上申请的key
url_values = urllib.parse.urlencode(data)
full_url = url0 + '?' + url_values
#print(full_url)
f = urllib.request.urlopen(full_url)
weatherHTML= f.read().decode('utf-8')#读入打开的url
weatherJSON = json.JSONDecoder().decode(weatherHTML)#创建json
#print(weatherHTML)
#print(weatherJSON)
print('========================')
results = weatherJSON['results']
print("当前城市:",results[0]['currentCity'])
#当天的天气建议
index = results[0]['index']
