Solving the Issue of Non-Responsive Python requests Library

When working with Python's requests library, you might encounter a frustrating scenario: your code runs without any output, leaving you scratching your head as to what went wrong. This guide aims to dissect this issue and provide a clear roadmap to resolving it. Let’s take a look at a common problem faced by developers and how to troubleshoot it effectively.

The Problem

A user recently described their problem: they were trying to send a request to a URL using the requests library along with custom headers. Despite executing the command, there was no output in the terminal. Their code snippet looked like this:

Despite running this code, there was no response. The user ensured they had an active internet connection and even tried different URLs, but the issue persisted.

The Solution

Understanding the Issue

When sending requests using the requests library, if you're using headers (like the ones in the initial code), you need to explicitly specify these headers in your request call. Failing to do so might cause the request to hang or return unexpected results.

Applying the Correct Headers

By including the headers parameter in the get() function, we ensure that the custom headers are sent along with the request, which can affect how servers respond to the request.

Checking the Output

After modifying the request to include headers, the user should be able to see the output:

A status code of 200 indicates a successful request, meaning that the request was received and processed correctly by the server.

Additional Tips for Troubleshooting

Check Your Internet Connection: Before diving into the code, ensure your internet connection is stable. Sometimes connectivity issues can impact request responses.

Use Timeouts: Utilize the timeout parameter in your request to prevent hanging. For example:
