This cleared so much @Stefan, thank you. I just need some clarification if you don't mind. In (1), when you say "import an extension module that you write", do you mean the Python library that was created "import emb"? Is that gonna be written in Cython or standalone .C file? in (2), what do to mean when you said "Use the Smalltalk C-API from your Cython code to call into Smalltalk and exchange data with it."? Please advise, Thank you so much for your help. -- https://mail.python.org/mailman/listinfo/python-list
