Our goal is that the Python C API is:

• Useful: It should provide access to all relevant functionality.
• Ergonomic: It should be easy to use.
• Fair: It should serve the purposes of a variety of stakeholders.
• Stable: It should avoid requiring users to update their code more than necessary.
• Evolvable: It should give Python implementers enough freedom to change implementation details.
• Maintainable: It should be easy to maintain and extend.
