What is the class attribute of your (misnamed) x.pt argument? If it does not inherit from class "func" then your plot.func method will not be used when you call plot(). You would need to explicitly call plot.func() instead. If this question/comment makes no sense to you, then you have some serious homework to do before you post further. Otherwise, follow the advice you have been given.
