Python interpreter - return JSON created in Python script back to C++ application

[luz-arreola]

Please bear with me...I've never used Python before. I am currently able to execute the following script from within my C++:

hello.py

import json
x =  { "name":"John", "age":30, "city":"New York"}
return json

I want my C++ code to execute the Python script and for the script to return JSON.

This is what I currently have:

C++ code:

std::string script = readFile("./cl/stencils/hello.py");
pybind11::scoped_interpreter guard{};
pybind11::exec(script);

How do I obtain this json from within my C++ application?

Thank you!

I was not able to obtain the json object returned by the python script but it is accessible to my C++ code using pybind11::dict which worked just fine.

you could also do json.dumps(myDict) and then return that as string & load using nlohmann::parse back in to json if ur json had mixt types/etc.
