Tkinter button in for

[Simpsunt]

Well that's kind of what I had in mind...

So I changed my code and now it works but it's awful :(

        keys = []
        names = []
        for key, name in self.__model.get_6_users().items():
            keys.append(key)
            names.append(name)
        for i in range(len(keys), 6):
            keys.append('-')
            names.append('-')
        Button(acceuil, text=names[0], command=lambda: self.click_user(keys[0])). \
            grid(column=0, row=2, sticky=N + S + W + E)
        Button(acceuil, text=names[1], command=lambda: self.click_user(keys[1])). \
            grid(column=1, row=2, sticky=N + S + W + E)
        Button(acceuil, text=names[2], command=lambda: self.click_user(keys[2])). \
            grid(column=2, row=2, sticky=N + S + W + E)
        Button(acceuil, text=names[3], command=lambda: self.click_user(keys[3])). \
            grid(column=3, row=2, sticky=N + S + W + E)
        Button(acceuil, text=names[4], command=lambda: self.click_user(keys[4])). \
            grid(column=4, row=2, sticky=N + S + W + E)
        Button(acceuil, text=names[5], command=lambda: self.click_user(keys[5])). \
            grid(column=5, row=2, sticky=N + S + W + E)
        for i in range(0,len(keys)):
            if keys[i] == '-':
                Button(acceuil, text=names[i], state=DISABLED).grid(column=i, row=2, sticky=N + S + W + E)

So I get my keys and names that I put in two != lists and I and values '-' if I don't have enough user to fill the 6 fields.
Then I create my 6 buttons.
Finaly I overwrite the buttons where '-' is set

If you have any better suggestions...?
