Flit
Flit is a simple tool for packaging and publishing Python packages to PyPI (Python Package Index). It streamlines the process by automating metadata management, building distributions, and handling uploads, making it easier for developers to share their Python libraries. It focuses on minimal configuration and is particularly well-suited for pure-Python packages.
Developers should learn Flit when they need to quickly package and distribute Python libraries, especially for small to medium-sized projects where complex setup is unnecessary. It's ideal for use cases like open-source contributions, internal tool sharing, or educational purposes, as it reduces boilerplate and simplifies publishing workflows compared to traditional tools like setuptools.
