各位前辈大大好：
我在练习抓天气网站的资料，可是照着API教学却出现错误讯息，
请大大帮忙看一下是哪边做错，感谢~
程式码：
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()
错误讯息：
requests.exceptions.HTTPError: 401 Client Error: Unauthorized for url:
http://api.openweathermap.org/data/2.5/forecast/daily?q=Taipei&cnt=3
天气网站API设定教学：
https://openweathermap.org/forecast16
Examples of API calls: Call 7 days forecast by city name
api.openweathermap.org/data/2.5/forecast/daily?q=London&cnt=7
