I tried to run a short program from the book Automate The Boring Stuff With Python, and, my result doesn't match the result predicted by the book. Here's the code:

import requests,json,sys

APPID ='7b26c92417fd3678d52eac12dc870222'

if len(sys.argv) < 2:
    print('Usage: getOpenWeather.py city_name, 2-letter_country_code')
    sys.exit()
location = ''.join(sys.argv[1:])

#Download the JSON data from OpenWeatherMap.org's API.
url = f'https://api.openweathermap.org/data/2.5/forecast/daily?q={location}&cnt=3&APPID={APPID}'
response = requests.get(url)
response.raise_for_status()

#Uncomment to see the raw JSON text:
#print(response.text)

#Load JSON data into a Python variable.
weatherData = json.loads(response.text)

#Print weather descriptions
w = weatherData['list']
print('Current weather in %s:'%(location))
print(w[0]['weather'][0]['main'],'-',w[0]['weather'][0]['description'])
print()
print('Tomorrow:')
print(w[1]['weather'][0]['main'],'-',w[1]['weather'][0]['description'])
print()
print('Day after tomorrow:')
print(w[2]['weather'][0]['main'],'-',w[2]['weather'][0]['description'])

The response I got was:

Traceback (most recent call last):
  File "C:\Users\Vesna\PycharmProjects\getOpenWeather.py", line 13, in <module>
    response.raise_for_status()
  File "C:\Users\Vesna\AppData\Roaming\Python\Python39\site-packages\requests\models.py", line 943, in raise_for_status
    raise HTTPError(http_error_msg, response=self)
requests.exceptions.HTTPError: 401 Client Error: Unauthorized for url: https://api.openweathermap.org/data/2.5/forecast/daily?q=Belgrade,Serbia&cnt=3&APPID=7b26c92417fd3678d52eac12dc870222

Then I commented out the raise_for_status function, and added a print statement regarding the response object from the API call ( just uncommented it ), and got this instead:

{"cod":401, "message": "Invalid API key. Please see http://openweathermap.org/faq#error401 for more info."}
Traceback (most recent call last):
  File "C:\Users\Vesna\PycharmProjects\getOpenWeather.py", line 22, in <module>
    w = weatherData['list']
KeyError: 'list'

Both messages allude to the same perceived root cause: lack of valid API key. However, this is just not the case. According to the website I used ( open weather ), a few things could cause the given error ( 401 ): invalid API key, not enough time spent after generating your first key, and trying to access premium services. I did get a valid API key, and even generated another one just to test it out ( with no different result ), I waited hours after my first attempt, so the possibility of my key not yet having finished the process of authorization is minimal, and I've checked multiple time which API services I requested, and they were the free ones ( current weather ) ONLY.

I have no idea what could be causing this error, and would immensely appreciate it if anyone helped me out with this, if they spot or know something I don't.

So when I try to add my API key, I get an error message telling me its not valid. I have contacted openweathermap who confirmed it's an active key. I did a search and people have previously suggested to make sure there's no spaces which I have done and I'm still getting the error message. I've tried typing it in too instead of copy and pasting with no joy.

Thanks for any help!
