本文实例为大家分享了python实现自主查询实时天气的具体代码，供大家参考，具体内容如下

用到了urllib2 json 很简单的一个应用如下

python实现自主查询实时天气

获取城市编号

									#coding=utf-8 

									import urllib2 

									url1 = 'http://m.weather.com.cn/data3/city.xml'

									content1 = urllib2.urlopen(url1).read() 

									provinces = content1.split(',') 

									print content1 # 输出content1可以查看全部省份代码 

									result = '' 

									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() # 输出content2可以查看此省份下所有城市代码 

									  cities = content2.split(',') 

									  print content2 

									  for c in cities: 

									    c_code = c.split('|')[0] 

									    url3 = url % c_code 

									    content3 = urllib2.urlopen(url3).read() 

									    print content3 #content3是此城市下所有地区代码 

									    districts = content3.split(',') 

									    for d in districts: # 对于每个地区，我们把它的名字记录下来，然后再发送一次请求，得到它的最终代码： 

									      d_pair = d.split('|') 

									      d_code = d_pair[0] # 

									      if 5 == len(d_code): 

									        continue

									        temp=[d_code] 

									        temp.insert(4,0) 

									        d_code ="".join(temp) 

									      name = d_pair[1] # 名字 

									      url4 = url % d_code 

									      content4 = urllib2.urlopen(url4).read() 

									      print content4 

									      code = content4.split('|')[1] 

									      line = "%s:%s\n" % (name, code) 

									      result += line 

									      print name + ':' + code 

									f = file('./city', 'w') 

									f.write(result) 

									f.close()

findweather

									# -*- coding: utf-8 -*- 

									import urllib2 

									import json 

									city = {} 

									f =file('city','r') 

									src = f.readlines() 

									for line in src: 

									  line = line.split('\n')[0] 

									  name = line.split(':')[0] 

									  code = line.split(':')[1] 

									  city[name] = code 

									cityname = raw_input('请输入你要查询的城市名称:\n') 

									citycode = city.get(cityname) 

									print cityname 

									if citycode: 

									  try: 

									    url = ('http://www.weather.com.cn/data/cityinfo/%s.html' % citycode) 

									    content = urllib2.urlopen(url).read() 

									    data = json.loads(content) 

									    result = data['weatherinfo'] 

									    str_temp = ('%s\n%s ~ %s') % (result['weather'],result['temp1'],result['temp2']) 

									    print str_temp 

									  except: 

									    print '查询失败'

									else: 

									  print '没有找到该城市'
