How to execute readthedocs examples?

[ssooffiiaannee]

I'm struggling to execute the examples provided in
https://pybind11.readthedocs.io/en/stable/advanced/pycpp/object.html#available-wrappers

Would it be possible to provide command a command to execute those examples? How can we know the context of py in py::print?
is there somewhere a namespace py = pybind11; ?
