Input

import requests

Setup Variables

• url: URL of the API endpoint
• timeout: Timeout in seconds for the request
• response: Response to the requests. Usually in data

url = "https://api.example.com/endpoint"
timeout = 100
response = None

Model

Making a Request

try:
    response = requests.get(url, timeout=timeout)
    response.raise_for_status()  # Raises an exception if the response status code is not 2xx
    data = response.json()
    # Process the data
    print("Data retrieved successfully:", data)
except requests.exceptions.RequestException as e:
    # Handle connection errors, timeouts, and other request exceptions
    print("Error occurred:", e)
except requests.exceptions.HTTPError as e:
    # Handle HTTP errors (status codes 4xx and 5xx)
    print("HTTP Error occurred:", e)
except ValueError as e:
    # Handle JSON decoding errors
    print("JSON decoding error occurred:", e)
except Exception as e:
    # Handle any other unexpected exceptions
    print("An unexpected error occurred:", e)
