Дизайн класса Corona Virus с использованием шаблона Composite

Я написал следующий код с намерением сделать его составным шаблоном: Я не уверен, передал ли я здесь намерение составного шаблона. Хотя согласно UML-диаграмме составного шаблона есть компонентный, листовой и составной
Но я не уверен, что это действительный дизайн составного шаблона в смысле варианта использования.

# Component
# interface for objects in the composition of 
# leaf and composite nodes

class Component:
    # size of sequence
    def display(self):
        pass

# RNA sequence 
class RNALeaf(Component):
    def __init__(self, name, rna_sequence):
        self.__rna_sequence = rna_sequence
        self.__name = name
    def display(self):
        print("RNA sequence: " + self.__name + " " + str(self.__rna_sequence))


# Amino acid sequence        
class AminoAcidLeaf(Component):
    def __init__(self, name, amino_acid_sequence):
        self.__amino_acid_sequence = amino_acid_sequence
        self.__name = name

    def display(self):
        print("Amino Acid sequence: " + self.__name + " " + str(self.__amino_acid_sequence))

class Composite(Component): 
    def __init__(self):
        Component.__init__(self)
        self._children = list()

    def display(self):
        for child in self._children:
            child.operation()

    def add(self, component):
        self._children.append(component)

    def remove(self, component):
        self._children.remove(component)
