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。
