When testing code that outputs to the terminal through either standard out (stdout) or standard error (stderr), you might want to capture that output and make assertions on it. To do so, use contextlib.redirect_stdout() and contextlib.redirect_stderr() to redirect the respective output streams to in-memory buffers that you can then inspect and assert on.

In this tutorial, you'll preview the new static typing features in Python 3.12. You'll learn about the new syntax for type variables, making generics simpler to define. You'll also see how @override lets you model inheritance and how you use typed dictionaries to annotate variable keyword arguments.

Learn how Python 3.12 generics make type-hinting easier and clearer. Use the new syntax to enhance your code's structure and readability.

With the recent explosion of LLM tools, I often like to kill time fiddling with different LLM client libraries and SDKs in one-off scripts. Lately, I’ve noticed that some newer tools frequently mess up the logger settings, meddling with my application logs. While it’s less common in more seasoned libraries, I guess it’s worth rehashing why hijacking the root logger isn’t a good idea when writing libraries or other forms of reusable code.

We can run asyncio.gather() in the background by not awaiting the call to asyncio.gather(). The asyncio.gather() returns an asyncio.Future that does not have to be awaited. It is scheduled for execution in the asyncio event loop, along with all coroutines provided to the gather. Therefore, the caller is free to proceed with other activities and […]

We can run an asyncio event loop in a new thread by starting a new thread and configuring it to start or run an event loop. There are many approaches we can use to run an event loop in a new thread. The simplest is to configure a new thread to start an event loop […]

We can automatically handle exceptions in coroutines executed via asyncio.gather() by setting the “return_exceptions” argument to True. By default, if a coroutine is executed by asyncio.gather() fails with an unhandled exception, it will be propagated to the caller. Setting the “return_exceptions” argument to True will trap any unhandled exceptions and provide them as return values, […]
