Watch out for this common generator pitfall. What happens to a try/finally, with block, or async with block inside a generator if the generator isn't exhausted? Does the cleanup code still run? When and how does it run? In this video we take a look at the answers to these questions and learn how to avoid a common situation where cleanup code doesn't run when you want it to. ― mCoding with James Murphy (https://mcoding.io) PEP 533: https://peps.python.org/pep-0533/ Discussion on GH issue: https://github.com/python/cpython/issues/88684 Source code: https://github.com/mCodingLLC/VideosSampleCode SUPPORT ME ⭐ --------------------------------------------------- Sign up on Patreon to get your donor role and early access to videos! https://patreon.com/mCoding Feeling generous but don't have a Patreon?

They may be "large" in the sense that they use billions of parameters, but that doesn't mean you need to be a big company in order to run one. In fact, you can run some of the latest and greatest LLMs on your own machine, on your GPU, completely for free. We'll see how to do all that and more in this video using Docker Desktop!

The key to iteration in Python A key feature of Python is it's incredible support for lazy iteration. Defining and consuming lazy sequences in Python are easy. You can even define an infinite sequence like powers of 2 or prime numbers! To make working with iterables in Python even easier, Python provides some basic building blocks to help you compose iteration primitives in different ways, which is what the itertools module is for. This module comes with 21 different primitives (and many more recipes for how to combine them), which we go over in this video.

Get started in FastAPI, Starlette, and ASGI! How do startup and shutdown events work in FastAPI, Starlette, and other ASGI applications? ASGI defines startup and shutdown events through the "lifespan" of an application, which it models as a connection between the server and the app. In this video we see the right way to do it in FastAPI, Starlette, and then understand the lifespan connection type in general, which we use to build our own lifespan handler from scratch that mimics what FastAPI does. ― mCoding with James Murphy (https://mcoding.io) Source code: https://github.com/mCodingLLC/VideosSampleCode ASGI Spec: https://asgi.readthedocs.io/ App class video: https://youtu.be/ai7y--6ElAE SUPPORT ME ⭐ --------------------------------------------------- Sign up on Patreon to get your donor role and early access to videos! https://patreon.com/mCoding Feeling generous but don't have a Patreon?

To function or to class? According to the spec, an ASGI application is an async callable, but when we use FastAPI, Starlette, or other ASGI frameworks, that callable is hidden in plain sight. In this video, we see how it's possible to use an application class instead of a literal async def function, and we go over reasons for preferring the class approach. ― mCoding with James Murphy (https://mcoding.io) Source code: https://github.com/mCodingLLC/VideosSampleCode ASGI Spec: https://asgi.readthedocs.io/ SUPPORT ME ⭐ --------------------------------------------------- Sign up on Patreon to get your donor role and early access to videos! https://patreon.com/mCoding Feeling generous but don't have a Patreon?

Critical! ... or is it? CVE-2024-24576 is a freshly reported 10/10 critical CVE affecting Rust, Python, and many other programming languages on Windows that, if exploited, can allow a malicious user to execute arbitrary code as the current user. The 10/10 rating is the worst severity that can be given to a CVE. However, of 9 affected programming languages, 5 have chosen to either not fix the CVE or fix it only by updating their documentation. Let's take a look at this vulnerability, which appears to take advantage of programming languages improperly escaping arguments while creating sub-processes, understand how it's performed, and see why so many languages are choosing not to fix it. ― mCoding with James Murphy (https://mcoding.io) Source code: https://github.com/mCodingLLC/VideosSampleCode Python discussion: https://discuss.python.org/t/is-python-affected-by-cve-2024-24576/50740/1 NIST CVE details: https://nvd.nist.gov/vuln/detail/CVE-2024-24576 Rust advisory: https://blog.rust-lang.org/2024/04/09/cve-2024-24576.html Subprocess docs: https://docs.python.org/3/library/subprocess.html Subprocess source: https://github.com/python/cpython/blob/main/Lib/subprocess.py CreateProcessW docs: https://learn.microsoft.com/en-us/windows/win32/api/processthreadsapi/nf-processthreadsapi-createprocessw Security researcher blog post: https://flatt.tech/research/posts/batbadbut-you-cant-securely-execute-commands-on-windows/ SUPPORT ME ⭐ --------------------------------------------------- Sign up on Patreon to get your donor role and early access to videos! https://patreon.com/mCoding Feeling generous but don't have a Patreon?

You can't forget! Context managers (used with the "with" statement) and try-finally are both constructs in Python that help you ensure certain cleanup code runs even in the presence of exceptions. Becoming familiar with these constructs is important for developing good coding habits in Python. Don't put the burden of remembering how to do cleanup on yourself, use a context manager to let the object handle its own cleanup! In this video, we take a deep dive into the semantics of context managers and try-finally, including the basic examples, sharp corners (and how to avoid them!), as well as less common use-cases. ― mCoding with James Murphy (https://mcoding.io) Source code: https://github.com/mCodingLLC/VideosSampleCode With statement docs: https://docs.python.org/3/reference/datamodel.html#with-statement-context-managers Try-finally docs: https://docs.python.org/3/reference/compound_stmts.html#finally-clause Pythonizing Imgui video: https://www.youtube.com/watch?v=wh_W-veFpKU SUPPORT ME ⭐ --------------------------------------------------- Sign up on Patreon to get your donor role and early access to videos! https://patreon.com/mCoding Feeling generous but don't have a Patreon?

Step by step through your program. Debugging is an essential and unavoidable part of programming. Everyone writes bugs, and we'd like to get rid of them. Print statements are fine to a certain point, but live debugging is usually a better option. With live debugging, you can step through your program one statement at a time, and set breakpoints at interesting places to stop, view, and interact with the state of the program before it proceeds.

A logging tutorial. At some point, print statements aren't enough. When that time comes in Python, you should reach for the builtin logging package. It may be old (committed in 2002!), but it is the standard in Python. Unfortunately though, it being so old means that it's full of stuff you shouldn't use, it doesn't follow modern conventions like PEP8 coding style, and many tutorials are vastly outdated.

Zero, destroyer of things. We take for granted that 0 times anything equals 0. But why? You might think of counting numbers, but we use 0 for a lot of different systems like naturals, reals, modular arithmetic, function spaces, and in all these cases we still have 0 times anything equals 0. Something about 0 makes this happen in many different spaces. In this video we see the proof and discover why zero times anything equals zero! ― mCoding with James Murphy (https://mcoding.io) Ring axioms: https://en.wikipedia.org/wiki/Ring_(mathematics) SUPPORT ME ⭐ --------------------------------------------------- Sign up on Patreon to get your donor role and early access to videos! https://patreon.com/mCoding Feeling generous but don't have a Patreon?
