本文实例讲述了Python实现从百度API获取天气的方法。分享给大家供大家参考。具体实现方法如下：

复制代码 代码如下:__author__ = \’saint\’
import os
import urllib.request
import urllib.parse
import json
class weather(object):
    # 获取城市代码的uri
    code_uri = \”http://apistore.baidu.com/microservice/cityinfo?cityname=\”
    # 获取天气信息的uri
    weather_uri = \”http://apistore.baidu.com/microservice/weather?cityid=\”
    # 主处理逻辑
    def mainHandle(self):
        print(\”输入你要查询的天气：\”)
        city_name = input()
        uri = self.code_uri + urllib.parse.quote(city_name)
        ret = json.loads(urllib.request.urlopen(uri).read().decode(\”utf8\”))
        if ret[\’errNum\’] != 0:
            print(ret[\’retMsg\’])
            return False
        else:
            weather_uri = self.weather_uri + ret[\’retData\’][\’cityCode\’]
            data = json.loads(urllib.request.urlopen(weather_uri).read().decode(\”utf8\”))
            if data[\’errNum\’] == 0:
                ret_data = data[\’retData\’]
                output = \”城市名:\” + city_name + \”\\r\\n\”
                output += \”更新时间:\” + ret_data[\”date\”] + \” \” + ret_data[\”time\”] + \”\\r\\n\”
                output += \”天气:\” + ret_data[\”weather\”] + \” [\” + ret_data[\”WD\”] + ret_data[\”WS\”] + \”]\\r\\n\”
                output += \”当前温度:\” + ret_data[\”temp\”] + \” (\” + ret_data[\”h_tmp\”] + \” —> \” + ret_data[\”l_tmp\”] + \”)\\r\\n\”
                print(output)
                return True
            else:
                print(data[\’errMsg\’])
                return False
if __name__ == \”__main__\”:
    weather = weather()
    weather.mainHandle()

希望本文所述对大家的Python程序设计有所帮助。
