Discover how various Python tools and linters have adopted it as their primary configuration source, and understand why it's essential for library publishing, application building, and script/notebook development. Dive into the development life-cycle integration of build systems and package managers, examining tools like Hatch, Poetry, PDM, Flit, and Rye. Master dependency resolution and locking with .lock files for creating reproducible environments and CI environment caches that support large team development.
