What

The exercice requires to get current temperatures for a list of locations provided on the file capitals.json that consists on a list of objects like

{
  "CountryName": "Antarctica",
  "CapitalName": "N/A",
  "CapitalLatitude": "0",
  "CapitalLongitude": "0.000000",
  "CountryCode": "AQ",
  "ContinentName": "Antarctica"
}

by using the latitude and longitude values any weather API can provide this information and example using Open Meteo

$ curl https://api.open-meteo.com/v1/forecast?latitude=0&longitude=0&current_weather=true

Print a list for all countries with actual temperature at the coordinates specified like:

...
Bujumbura: 25.7°
Taipei: 21.9°
Saint Helier: 14.4°

San Salvador: 25.1°
Bamako: 36.5°
Libreville: 30.3°
Castries: 27.9°
Doha: 29.5°
...

Instructions
