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。
