Erreur : il manque un argument 'self'

from tkinter import *

class window2():
    def __init__(self):
        # fenêtre config gestionnaire

        window2 = Tk()
        window2.title("gestionnaire de mot de passe")
        window2.geometry("1350x750")
        window2.configure(bg='#4250DA')

        bouton = Button(window2)
        Button.place(x=10, y=100)

        window2.mainloop()

if __name__ == '__main__':
    window2()

TypeError: place_configure() missing 1 required positional argument: 'self'
