Python Requests Request Exception

If you are working with web scraping or API calls in Python, chances are you will come across exceptions. One of the most common exceptions is the "RequestException" that is raised by the Python Requests library.

What is the RequestException?

The RequestException is a Python Requests library exception that is raised when a request to the server fails for any reason. This exception is a catch-all for any exception that occurs during a request, such as a timeout, network errors, or invalid SSL certificates.

Using Try-Except Blocks

One way to handle the RequestException is by using a try-except block in your code. This block will catch any exceptions that occur during the request and allow you to handle them appropriately.


import requests

try:
    response = requests.get('http://example.com')
    response.raise_for_status()
except requests.exceptions.RequestException as e:
    print(e)

In this example, we are making a GET request to "http://example.com". If an exception occurs during the request, it will be caught by the except block and the error message will be printed to the console.

Using Raise for Status

Another way to handle the RequestException is by using the "raise_for_status()" method. This method will raise an HTTPError if the request returned an unsuccessful status code (e.g. 404, 500), or a RequestException if an error occurred during the request.


import requests

response = requests.get('http://example.com')
response.raise_for_status()

In this example, we are making a GET request to "http://example.com" and using the "raise_for_status()" method to handle any exceptions that occur during the request.

Conclusion

The RequestException is a common exception that you may encounter when working with the Python Requests library. By using try-except blocks or the raise_for_status() method, you can handle these exceptions and ensure that your code is robust and error-free.
