各位前輩大大好：
我在練習抓天氣網站的資料，可是照著API教學卻出現錯誤訊息，
請大大幫忙看一下是哪邊做錯，感謝~
程式碼：
location = ' '.join(sys.argv[1:])
# Download the JSON data from OpenWeatherMap.org's API.
url = 'http://api.openweathermap.org/data/2.5/forecast/daily?q=%s&cnt=3' %
(location)
response = requests.get(url)
response.raise_for_status()
錯誤訊息：
requests.exceptions.HTTPError: 401 Client Error: Unauthorized for url:
http://api.openweathermap.org/data/2.5/forecast/daily?q=Taipei&cnt=3
天氣網站API設定教學：
