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：

__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()
