Actually this is the way of doing scripting from Ada, like GPS IDE does. 
You write a module, e.g. in Ada, and then you can import it in your 
Python script. The module must be a DLL.

You could start with something like this:

project Python is
    for Languages use ("Python");
    package Compiler is
       for Driver ("Python") use
 
"C:/GNAT/2021/libexec/gnatstudio/gnathub/share/gnathub/python/python.exe";
       for Required_Switches ("Python") use ("-m", "compileall");
    end Compiler;
    package Naming is
       for Body_Suffix ("Python") use ".py";
    end Naming;
end Python;
