Codecov’s unreliability breaking CI on my open source projects has been a constant source of frustration for me for years. I have found a way to enforce coverage over a whole GitHub Actions build matrix that doesn’t rely on third-party services.

If you need to perform HTTP requests using Python, then the widely used Requests library is often the way to go. However, if you prefer to use only standard-library Python and minimize dependencies, then you can turn to urllib.request instead.

In this video course, you’ll:

• Learn the essentials of making basic HTTP requests with urllib.request
• Explore the inner workings of an HTTP message and how urllib.request represents it
• Grasp the concept of handling character encodings in HTTP messages
• Understand common hiccups when using urllib.request and learn how to resolve them

If you’re already familiar with HTTP requests such as GET and POST, then you’re well prepared for this video course. Additionally, you should have prior experience using Python to read and write files, ideally using a context manager.

In the end, you’ll discover that making HTTP requests doesn’t have to be a frustrating experience, despite its reputation. Many of the challenges people face in this process stem from the inherent complexity of the Internet. The good news is that the urllib.request module can help demystify much of this complexity.

Are you early in your software dev or data science career? Maybe it hasn't even really started yet and you're still in school. On this episode we have Sydney Runkle who has had a ton of success in the Python space and she hasn't even graduated yet. We sit down to talk about what she's done and might do differently again to achieve that success.
