Python C API summit at EuroPython 2025

We would like to invite anyone who is interested to the Python C API summit that will take place at EuroPython 2025 in Prague on Monday, July 14th, 2025, or Tuesday the 15th (the schedule is not final yet).

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

You will need to have a valid EuroPython in-person ticket (Conference, Tutorial or Combined) to participate.
All the info is up at the EuroPython site.

The number of participants may be limited. Please register using the form. If you are interested in giving a presentation, please include a short abstract in the registration form.
