Python interpreter as a c++ class

Question

I am working on embedding python in to c++. In some peculiar case I require two separate instances of the interpreter in same thread.

Can I wrap Python interpreter in to a c++ class and get services from two or more class instances?

Answer 1

You can, but I'd recommend you not to re-implement a Python interpreter when there is a standard implementation. Use boost::python to interface with Python.

Answer 2

Callin Py_Initialize() twice won't work well, however Py_NewInterpreter can work, depending on what you're trying to do. Read the docs carefully, you have to hold the GIL when calling this.

Answer 3

I don't think you are the first person to want to do this, unfortunately I believe it is not possible. Are you able to run the python interperters as separate processes and use RPC?

Answer 4

• You can let the python interpreter live outside of your application memory space. Just embed the interpreter in a DLL.
• You can set up & save python contexts to simulate two different interpreters.
