Standalone Python functions in UML?

I would say that within a class diagram, you can't. In other UML
diagrams (such as sequence interaction), the function is simply used as
if it were a method belonging to an object. If you need to make it
clear where this function is located within the code, use a note on the
diagram.

Remember, UML is not able to accurately capture all implementation
details of a system; It's not meant to.

Again, don't try to depict fine-grained implementation details. If the
dynamically generated class is important to the class diagram, include
it but don't include all of it's internals (methods etc.). Use a note
to exaplin how/when/why it is generated.
