本文實例講述了Python實現從百度 API獲取天氣的方法。分享給大家供大家參考。具體實現方法如下：

	__author__ = 'saint'

	import os

	import urllib.request

	import urllib.parse

	import json

	class weather(object):

	    # 獲取城市代碼的uri

	    code_uri = "http://apistore.baidu.com/microservice/cityinfo?cityname="

	    # 獲取天氣信息的uri

	    weather_uri = "http://apistore.baidu.com/microservice/weather?cityid="

	    # 主處理邏輯

	    def mainHandle(self):

	        print("輸入你要查詢的天氣：")

	        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 += "更新時間:" + ret_data["date"] + " " + ret_data["time"] + "\r\n"

	                output += "天氣:" + ret_data["weather"] + " [" + ret_data["WD"] + ret_data["WS"] + "]\r\n"

	                output += "當前溫度:" + 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()
