Also using Api's is easier when it comes to weather data, eg wttr.in or OpenWeather .

G:\div_code\hex
λ curl wttr.in/Zagrep?format=3
Zagrep: ☀️   +25°C 

In Python this curl command would be.

import requests

params = {
    'format': '3',
}
response = requests.get('http://wttr.in/Zagrep', params=params)
print(response.text)

Output:
Zagrep: ☀️   +25°C
