如何使用weatherstack.com api

Question

嗨，我对python很陌生。我试着用rasa做一个聊天机器人供个人使用。现在想添加天气api。我使用weatherstack.com。如果我使用他们的例子，这是可行的，但如果我根据自己的喜好调整它，我总是以同样的错误告终

condition = api_response['current']['weather_descriptions'] TypeError: list indices must be integers or slices, not str

这是我正在使用的代码

class Actionweatherapi(Action):
    def name(self):
        return "actions.weatherapi"

    def run(self, dispatcher, tracker, domain):
        import requests
        location = tracker.get_slot('location')
        if location == 'None':
            location = 'fetch:ip'
        api_result = requests.get('http://api.weatherstack.com/current?access_key=0000000&query={}'.format(location))
        api_response = api_result.json()
        country = api_response['request']['query']
        condition = api_response['current']['weather_descriptions']
        temperature_c = api_response['current']['temperature']
        humidity = api_response['current']['humidity']
        wind_mph = api_response['current']['wind_speed']
        response = """It is currently {} in {} at the moment. The temperature is {} degrees, the humidity is {}% and the wind speed is {} mph.""".format(condition, country, temperature_c, humidity, wind_mph)
        dispatcher.utter_message(response)
        return [AllSlotsReset()]

我还回顾了python网站上的printf样式的字符串格式，但我不知道如何让它工作

json响应类似于此示例 http://api.weatherstack.com/current?access_key=1c80e8b9fe4fcef4f8d6fd7514a8e9e9&query=New%20York
