For loop in my __init__ doesn't work as expected

[Jessy]

 class DictionnaireOrdonne:
        """Classe permettant de créer un dictionnaire ordonné comme une liste, avec des indices"""

        def __init__(self, **keys_values):
            """classe prennent un nombre indéfinit de paramètres nommées"""

            self.keys_values = keys_values
            self._dictionnaire = self.keys_values
            for keys in self.keys_values:
                self.keys = keys

        def __repr__(self):
            """Cette méthode est appelée quand on appelle l'objet"""

            return str(self.keys_values)

        def __getitem__(self, key):
            """Cette méthode spéciale est appelée quand on fait objet[index]
                    Elle redirige vers self._dictionnaire[index]"""

            return self._dictionnaire[key]

        def __setitem__(self, key, value):
            """Cette méthode est appelée quand on écrit objet[index] = valeur
                    On redirige vers self._dictionnaire[index] = valeur"""

            self._dictionnaire[key] = value


test = DictionnaireOrdonne(one=1, two=2, three=3)
print(test.keys)

When I run this code, I get:

Output:
three

I only get one of the 3 keys, and it's the last one, i don't know why.

However, when if I modify my for loop to this:

for keys in self.keys_values:
        print(keys)

Then I get:

Output:
one
two
three

I get the output wanted, but I can't use it because it will print itself without me calling it.

Why do I get only get one key in my first example, and how can I make it so that I get my three keys when I call test.keys?

When you loop through a dictionary, each time through the loop you get one key. You assign that to self.keys, but each time you do it, you overwrite what was there before. So whatever the last key is, that's what self.keys ends up as.

If you want all of the keys, I would suggest self.keys = list(self.key_values.keys())

[buran]

when you do self.keys there is one attribute keys. In the loop you continuously override previously assigned value of that attribute, so the last value is the last key (three).
When you iterate over dict you itetrate over dict.keys(). So when you amend the code, you simply print the keys of keys_values dict.
