API-TypeError：列表索引必须是整数，而不是str

Question

All the variables that store the API data:

formatted_data = json_data['list'][0]['main'] # Extracting the main description from the API
formatted_data3 = json_data['list'][0]['weather']['description'] # Extracting the weather description from the API
formatted_data2 = json_data['list'][0]['main']['temp'] # Extracting the temperature description from the API
formatted_data4 = json_data['list'][0]['main']['temp_min']
formatted_data5 = json_data['list'][0]['main']['temp_max']
formatted_data6 = json_data['list'][0]['clouds']['all']

Can anyone help me out with this error?

Traceback (most recent call last):
File "MainWeatherAPI.py", line 21, in <module>
print(ForecastAPIFunction.getForecast(city, country))
File "/home/codio/workspace/Weatherbot/ForecastAPIFunction.py", line 
13, in getForecast
formatted_data3 = json_data['list'][0]['weather']['description'] 
#Extracting the weather description from the API

EDIT:

Code that is relevant to what I have tried so far:

while True:
    address = input("Address: ")
    if address == 'quit' or address == 'q':
        break
    url = main_api + urllib.parse.urlencode({'address': address}) 
    json_data = requests.get(url).json() 
    #print(url)
    json_status = json_data['status'] print('API Status: ' + json_status + '\n')
    if json_status == 'OK':
        for each in json_data['results'][0]['address_components']:
            print(each['long_name'])

EDIT:

Sample API data that correlates to all the variables that I have used to store the data. This is also relevant to the error that I am receiving.

Answer 1

try this

formatted_data3 = json_data['list'][0]['weather'][0]['description'] 

the weather element is array as well
