Meet the Community

The main goal of this summit is for various stakeholders of Python’s C API to meet and discuss about the state of the API, existing challenges and ongoing work.

We are particularly looking for contributors and maintainers of:

• Python implementations with a C API (e.g., CPython, PyPy, GraalPy, MicroPython)
• Binding generators and alternative APIs (e.g., HPy, Cython, pybind11, PyO3, SWIG)
• Libraries that use the C API heavily or in innovative ways
• Applications that embed Python
• Similar projects working in this area
