Python解析和迭代json d

Question

#current forecast
current_api = 'api.openweathermap.org/data/2.5/weather?zip='
current_url_zip = current_api + urllib.parse.urlencode({'Zip': zip})
#current_url_key = 

json_data = requests.get(future_url_key).json()

#print (json_data)
future_temp_day_0 = json_data['list'][0]['main']['temp'] #current day
future_temp_day_1 = json_data['list'][1]['main']['temp'] #tomorrow
future_description_day_0 = json_data['list'][0]['weather']['description'] #current description
future_description_day_1 = json_data['list'][1]['weather']['description'] #current description
#Kelvin to F conversion
fTemp_0 = int((future_temp_day_0 - 273.15) * (9/5) + (32))
fTemp_1 = int((future_temp_day_1 - 273.15) * (9/5) + (32))

所以我使用的是OpenWeatherMapAPI。我想能够拉今天[温度][天气描述]和明天[温度][天气描述]。问题是当我尝试引用[weather description]时，它从json_data['list'][3]而不是json_data['list'][1]中提取它。它迭代到下一个点，即使我引用的是[1]项。你知道吗

Answer 1

weather键包含一个dict列表，因此如果需要列表第一个条目的描述，应该使用[0]：

future_description_day_0 = json_data['list'][0]['weather'][0]['description']
future_description_day_1 = json_data['list'][1]['weather'][0]['description']
