Exceptions in Requests Python

Requests is a popular Python library used to make HTTP requests. It provides an easy-to-use interface to send HTTP/1.1 requests extremely easily. It supports GET, POST, PUT, DELETE, OPTIONS, CONNECT, TRACE and many more request methods.

Exception Handling in Requests

When making HTTP requests in Python using requests library, you may encounter some exceptions which are used to handle certain errors. Here are some of the most commonly used exceptions in requests:

  • requests.exceptions.RequestException: This is a base class for all exceptions in the requests library. If any exception is raised, it will be an instance of this class.
  • requests.exceptions.ConnectionError: This exception is raised if a connection cannot be established to the target URL.
  • requests.exceptions.HTTPError: This exception is raised if the response from the server is not successful (i.e., 4xx or 5xx status code).
  • requests.exceptions.Timeout: This exception is raised if the request times out before a response is received.
  • requests.exceptions.TooManyRedirects: This exception is raised if the request exceeds the maximum number of allowed redirects.
  • requests.exceptions.URLRequired: This exception is raised if a valid URL is not provided to the request method.

Example of Exception Handling in Requests


import requests

try:
    # Send a GET request to the URL
    response = requests.get('https://www.example.com', timeout=5)

    # Check if the response was successful
    response.raise_for_status()

    # Print the content of the response
    print(response.content)

except requests.exceptions.RequestException as e:
    print(f"Error: {e}")

In conclusion, exceptions in requests Python are used to handle errors that may occur during HTTP requests. By understanding these exceptions and handling them properly, you can ensure that your Python code is more robust and less prone to errors.
