Python Requests Module raise_for_status

If you are using Python for web development or web scraping, you would have probably come across the Python Requests module. It is a popular library that allows you to make HTTP requests and handle the response.

One of the methods that the Requests module provides is raise_for_status. This method is used to raise an HTTPError exception if the response status code is not in the range of 200-299.

Here's an example:


import requests

response = requests.get('https://www.google.com')
response.raise_for_status()

print(response.content)

In this example, we are making a GET request to Google's homepage using the Requests module. After receiving the response, we call the raise_for_status method. If the response status code is anything other than 200, an HTTPError exception will be raised.

This is a useful feature because it allows you to handle errors in a more graceful manner. Instead of checking the response status code manually and raising an exception yourself, you can let Requests do it for you.

Other ways to handle errors

While raise_for_status is a convenient method for handling errors, there are other ways to handle errors with the Requests module.

  • You can use the status_code attribute of the response object to check the status code manually.
  • You can use a try-except block to catch exceptions and handle them appropriately.

Here's an example of using the status_code attribute:


import requests

response = requests.get('https://www.google.com')

if response.status_code == 200:
    print(response.content)
else:
    print('Error:', response.status_code)

In this example, we are checking the status code manually using the status_code attribute. If the status code is 200, we print the response content. Otherwise, we print an error message with the status code.

Using a try-except block is another way to handle errors. Here's an example:


import requests

try:
    response = requests.get('https://www.google.com')
    response.raise_for_status()
    print(response.content)
except requests.exceptions.HTTPError as e:
    print('Error:', e)

In this example, we are using a try-except block to catch any HTTPError exceptions that might be raised. If an exception is raised, we print an error message with the exception. Otherwise, we print the response content.
