Python类型错误:列表索引必须是整数或切片，而不是str，Django 3.1 CLOSED

Question

city_info = {
'city': city,
'temp': res['main']['temp'],
'weatherDescription': res['weather']['description'],
'icon': res['weather']['icon'],
'windSpeed': res['wind']['speed'],
}

为什么当我调用OpenWetherMap API的"天气"对象时，我会出现以下错误：

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

我使用的是Python 3.8.2和Django 3.1

完整代码，如下所示：

from django.shortcuts import render
import requests
def index(request):
# This is MINE API key! You can change it to yours, if you need it.
apiKey = '8bf70752121d2f2366e66d73f3445966'
url = 'https://api.openweathermap.org/data/2.5/weather?q={}&units=metric&appid=' + apiKey 
city = 'Washington'
res = requests.get(url.format(city)).json()
city_info = {
'city': city,
'temp': res['main']['temp'],
'weatherDescription': res['weather']['description'],
'icon': res['weather']['icon'],
'windSpeed': res['wind']['speed'],
}
context = {'info': city_info}
return render(request, 'weather/index.html', context)

Answer 1

res['weather']是一个包含字典的列表，因此只需执行以下操作：

city_info = {
'city': city,
'temp': res['main']['temp'],
'weatherDescription': res['weather'][0]['description'],
'icon': res['weather'][0]['icon'],
'windSpeed': res['wind']['speed'],
}
