#Create & Configure frame 
frame=Frame(root)
frame.grid(row=0, column=0, sticky=N+S+E+W)

#Create a 5x10 (rows x columns) grid of buttons inside the frame
for row_index in range(5):
    Grid.rowconfigure(frame, row_index, weight=1)
    for col_index in range(10):
        Grid.columnconfigure(frame, col_index, weight=1)
        btn = Button(frame) #create a button inside frame 
        btn.grid(row=row_index, column=col_index, sticky=N+S+E+W)  

root.mainloop()
