I can’t help mentioning my own project - https://github.com/aldanor/ipybind https://github.com/aldanor/ipybind - which provides a lightweight Jupyter interface to pybind11 [1], allowing to quickly sketch working C++ extensions in the notebook; all features of pybind11 like numpy support are immediately available. Been using it myself quite a lot for prototyping C++/Python code. [1] https://github.com/pybind/pybind11 https://github.com/pybind/pybind11
