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
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'
运行 findweather 即可。
