tkinter buttons not displaying

I added the suggestions in the comments to your code and removed some unrelated lines (to the problem). Now the buttons show:

1. Remove the events argument from the Buttons method.

2. Add self.Buttons() to self.__init__

Minimal working (solved) example.

from tkinter import *class App(Frame):    def __init__(self, master):        Frame.__init__(self, master)        self.columnconfigure(0, weight=1)        self.rowconfigure(0, weight=1)        self.pack(fill='both', expand=True)        self.bind("<Configure>", self.resize)        self.Buttons()  # <--------------------- IMPORTANT!    def resize(self, event):        size = (event.width, event.height)    def Buttons(self):  # <--------------------- Remove the event argument        self.Button1 = Button(master=self, text="OLD VINS")        self.Button1.grid(row=1, column=1)        self.Button2 = Button(master=self, text="QBAY")        self.Button2.grid(row=2, column=1)        self.Button3 = Button(master=self, text="HELP")        self.Button3.grid(row=3, column=1)root = Tk()app = App(root)app.mainloop()
