Penanganan kesalahan

Jenis kesalahan
- Kesalahan koneksi
- Kesalahan HTTP
  - 4XX Kesalahan klien
  - 5XX Kesalahan server
Menangani kesalahan dengan kode status

Menangani kesalahan dengan exception
- raise_for_error()

import requests
from requests.exceptions import ConnectionError, HTTPError

try:
    response = requests.get("http://api.music-catalog.com/albums") 
    response.raise_for_status()

except ConnectionError as conn_err: 
    print(f'Connection Error! {conn_err}.')

except HTTPError as http_err:
    print(f'HTTP error occurred: {http_err}')
