Since Smalltalk does not support Python directly I have to settle with the C/Python API (https://docs.python.org/3.6/extending/embedding.html#beyond-very-high-level-embedding-an-overview). Any suggestions?

For right now, I need to call a .so file from Smalltalk. I can't explicitly use Python libraries since Smalltalk does not support Python. I need to use the C/Python API (in Smalltalk) to create a bridge where I can call a .so and a function in that .so file with a PyObject (This will be called back to Smalltalk from the .so file). I can't figure out a way to do that since the C/API can't call C or .so files.
sorry for the confusion on my part
