What tools or systems do you use for compiling and building your projects?

The following tools are commonly used for compiling and building Python projects:

• setuptools and distutils — standard libraries for packaging and installing packages.
• pip — for installing dependencies and building wheel packages.
• tox — for automating testing and building in different environments.
• poetry — a modern tool for dependency management and project building.
• make or invoke — for writing build scripts and automating tasks.

The choice depends on the complexity of the project and the build requirements.
