Understanding and Fixing the "Max Retries Exceeded" Error in Python Requests
When working with URLs in Python, specifically using the requests library, you may encounter various issues, particularly when checking the validity of a URL. One common error that arises is the Max retries exceeded with url error, often accompanied by a ConnectionError. In this guide, we will delve into understanding this problem and how to remedy it effectively in your Python scripts.
The Problem
Imagine you are executing a script to check multiple URLs and suddenly, one URL takes longer than expected. Eventually, you face an error like this:

This error can be frustrating as it halts your program, especially when most URLs are functioning correctly. The root cause is typically a failure to establish a connection due to server unavailability or network issues, leading to a time-out.
The Solution
To address this problem effectively, you need to modify your error-handling strategy in your script. Here’s a structured breakdown of what needs to be done:
1. Understand the Exceptions
When dealing with network requests, you may encounter several exceptions that can interrupt the flow of your program:
requests.exceptions.ConnectionError: Raised when the connection to the server fails.
requests.exceptions.Timeout: Raised when the request exceeds the time limit set for it.
requests.exceptions.RequestException: A generic exception for all request-related errors.
2. Modify Your Error Handling
Instead of only catching specific exceptions, broaden your scope to handle all relevant ones. Here’s how you can adjust your try-except blocks in your existing code:

3. Implementing the Changes in Your Code
Using the structured error handling approach shared above, update your Checking_for_http_https_content_status method accordingly. Here’s how you could revise your code:

Final Thoughts
By implementing these changes, you can ensure your script handles connection errors gracefully, effectively skipping over problematic URLs without crashing your program. In summary:
Understand which exceptions can occur.
Broaden your error-handling to include all relevant exceptions.
Update your code structure to implement these changes.
This not only enhances the robustness of your code but also improves your overall efficiency when working with URL validations in Python.
