源代码如下，可以再pycharm直接运行

# 解析天气接口，获取某一个城市的天气预报

            for weather_data in weather_datas:

            while True:
                city = input("输入查询城市（q退出）")
                if city == 'q':
                    break
                else:
                    self.get_city_weather(city)
    
    
    if __name__ == '__main__':
        weather = Weather()
        weather.start_query()

首先显示的是本地天气

输入城市：
