Let's say I have a jupyter notebook with both python and julia. In julia i have a variable
var_julia = 10
and in python I have
var_python = 20
What I would like to do is to efficiently (without any JSONs nor CSVs) transfer these 2 variables between, so I can print var_julia in python and var_python in julia. How should I do that?
Basically using the forementioned PyCall PyJulia you can do:
var_python = 10
%%julia
py"var_python"
and for the other way round:
var_julia = 20
new_var = %julia var_julia
print(new_var)
Have a look at PythonCall and JuliaCall which should cover your use case.
There's also PyCall.jl for the "call Python from Julia" direction and PyJulia for the "call Julia from Python" direction.
