Standalone Python functions in UML?

[Roman Susi]

Hi!

Out of curiosity, how do I draw functions outside classes with UML? How 
module could be drawn in this case?

More theoretical question is if I create classes on the fly, how UML can 
reflect that?

(I know that Python code itself is best at communication design ideas, 
but there are some people which prefer to talk UML.)

(Have not found anything relevant with google)

Thanks!
