Method returns TypeError: list indices must be integers or slices, not str

Question

我正在使用 openweathermap 获取天气数据，其中 returns 一个 JSON 对象如下：

blank = {
    "coord": {"lon": -92.11, "lat": 46.78},
    "weather": [
        {"id": 800, "main": "Unknown", "description": "Unknown", "icon": "01d"}
    ],
    "base": "stations",
    "main": {
        "temp": 0,
        "feels_like": 0,
        "temp_min": 0,
        "temp_max": 0,
        "pressure": 0,
        "humidity": 0,
    },
    "visibility": 0,
    "wind": {"speed": 0, "deg": 0},
    "clouds": {"all": 1},
    "dt": 0,
    "sys": {"type": 1, "id": 3903, "country": "US", "sunrise": 0, "sunset": 0},
    "timezone": 0,
    "id": 0,
    "name": "Unknown",
    "cod": 0,
}

我在 ["weather"]["description"] 上返回字符串时遇到问题这将引发类型错误 TypeError: list indices must be integers or slices, not str

方法：

class OpenWeather:
    def descrip(self):
        return self.data["weather"]["description"]

有人有什么建议吗？

Answer 1

应该是

class OpenWeather:
    def descrip(self):
        return self.data["weather"][0]["description"]
        #                          ^^^

或者某种列表理解，因为 weather 是一个列表（可能是字典列表，但您的示例只包含一个字典）。
