This file tells tools like pip and build how to create your project

[build-system]
requires = [
    "setuptools>=42",
    "wheel"
]
build-backend = "setuptools.build_meta"

build-system.requires gives a list of packages that are needed to build your package. Listing something here will only make it available during the build, not after it is installed.

build-system.build-backend is the name of Python object that will be used to perform the build. If you were to use a different build system, such as flit or poetry, those would go here, and the configuration details would be completely different than the setuptools configuration described below.

Setup.cfg setup

Using setup.cfg is a best practice, but you could have a dynamic setup file using setup.py

[metadata]

Running the build

Make sure your build tool is up to date

Windows

py -m pip install --upgrade build

Linux/MAC OS

python3 -m pip install --upgrade build

Create the build

py -m build
