PythonNet define module from string - python.net

Question

I'm using PythonNet to call a Python script from within a C# code.
I would like to define a module in a string variable (like myModule in the code below) and to be able to import that module and use its functions later:
using (Py.GIL())
{
// create a Python scope
using (PyScope scope = Py.CreateScope())
{
string myModule = #"# a lot of fancy Python code"; // Define a module here
// Here I'd like to register myModule as a module,
// to be used later within this scope: what shall I do?
string script = #"import myModule as functions"; // import and use the module here
scope.Exec(script);
...
string s = scope.Eval<string>(...);
return s;
}
}
How can this be achieved?

The PyScope class defines an overload of Import that accepts a PyScope and a string as parameters.
First, execute your module in a scope (moduleScope), then you can import it in a second scope
using (PyScope moduleScope = Py.CreateScope())
{
string myModule = #"# a lot of fancy Python code"; // Define a module here
moduleScope.Exec(myModule);
// create a Python scope
using (PyScope scope = Py.CreateScope())
{
scope.Import(moduleScope, "functions");
double d = scope.Eval<double>("functions.my_variable");
...
