Python 3.15a7, which is now just a uv python install 3.15 away on all major platforms, has lazy imports! This exciting feature, proposed in PEP 810, promises to make CLI applications faster (especially when using flags like --help), and could make a lot of large code with lots of imports that don’t always get used faster too. Unlike the earlier, failed attempt, this requires libraries to put in some work. I’ve developed a helper tool to make it easy; I’d like to cover what lazy imports are and how to use my tool. Since this is the first library that I used AI heavily in developing, the second half of the post will cover how my experience with AI for a task like this went.
TL;DR: run uvx flake8-lazy --apply=list to make your code magically faster on Python 3.15!

TLDR

We all love Python’s comprehensive standard library, but let’s face it – PyPI’s wealth of packages often becomes essential. Sharing single-file, self-contained Python scripts that rely on these external tools can be a headache. Historically, we’ve relied on requirements.txt or full-fledged package managers such as Poetry or pipenv, which can be overkill for simple scripts and intimidating for newcomers. But what if there was a simpler way? That’s where uv and PEP 723 come in. This article delves into how uv harnesses PEP 723 to embed dependencies directly within scripts, making distribution and execution extremely easy.
