Where I can find more info / doc about calling Python code from C#?

I modified the sample code which has "def function():".
string name = "world";
var eng = IronPython.Hosting.Python.CreateEngine();
var scope = eng.CreateScope();
eng.Execute($@"
def greetings():
return 'Hello {name}'!'

greetings();
", scope);
dynamic greetings = scope.GetVariable("greetings");
var result = greetings( ); // this will crash.

I figure it out. Thanks.
