Object Oriented programming (OOP) problem

[OmegaRed94]

This starts with a blank class and adds attributes.

class Blank():
    pass

class NotBlank():
    def __init__(self):
        self.a = 1
        self.b = 2.0
        self.c = 'three'

def only_these_types(types, source_object):
    blank = Blank()
    for name, value in source_object.__dict__.items():
        if type(value) in types:
            setattr(blank, name, value)
    return blank


for name, value in only_these_types((int, str), NotBlank()).__dict__.items():
    print(name, value)

Something like this would only work for a "data class". The new object has none of the method attributes of the source class.

Thanks
