I am creating a basic management system, made in python and tkinter, in which it already looks good visually, but when I am trying to create a def add_Residentes_no(self), and I paste it in this part that says Addbtn = Button(btn_frame, text =”Register”, width=10,command=self.add_Residentes_no).grid(row=0, column=0, padx=10, pady=20),

It tells me that the AttributeError: ‘UDI’ object has no attribute ‘add_Residentes_no’. Did you mean: ‘Residentes_no’?, but in the tutorial I’m following, the guy doesn’t get this error, does anyone know why that might be? :C

This is supposed to allow me to start connecting the database, but instead I got this error, which the def does not want to enter, I really need help guys :C
