Keep getting the id from items in a list which is in a class

class EditorState:
    def __init__(self, content):
        self.content = content

class Editor:
    def __init__(self):
        self.content = ""

    def __str__(self):
        return f'{self.content}'

    def setContent(self, value):
        self.content = value

    def createContent(self):
        return EditorState(self.content)

    def restore(self, new_value):
        self.content = new_value

    def getcontent(self):
        return self.content

class History:
    def __init__(self):
        self.history = []

    def __repr__(self):
        return self.history

    def push(self, value):
        self.history.append(value)

    def remove(self):
        my_list = self.history
        my_list.pop()

        last_index = my_list[-1]
        return last_index

    def getvalue(self):
        my_list = self.history
        return self.history

I've learned how to use the Memento pattern in java, and I wanted to try the pattern with python. I does work but the problem is that when I'm returning the last item from my list in the history class, so it keeps showing me its id not the value. It's the same when I print the list using the getvalue() method.

I've tried to use the magic methods sush as str or repr but it did'nt work, also I've tried to set the attribut to a variable but no results.
