What is the structure of a pyproject.toml file?

The pyproject.toml file is used for Python project configuration. It typically includes sections like [build-system], [tool], and [project]. Each section has specific keys and values that define dependencies, build requirements, and project metadata.

Can you explain what goes into the [tool] section?

Sure! The [tool] section is where you can specify configurations for various tools used in your project, like linters or formatters. For example, you might have [tool.black] to configure the Black code formatter.

What about the [build-system] section?

The [build-system] section defines the build requirements for your project. It typically includes the 'requires' key for specifying dependencies and the 'build-backend' key to indicate the build system being used, like setuptools.

Are there any best practices for organizing this file?

Yes, it's best to keep your pyproject.toml file organized by grouping related settings together, using comments for clarity, and ensuring that you only include necessary dependencies to keep the file clean.
