There's the code I have:

import tkinter

class GuiEl(tkinter.Button):
    def __init__(self):
        self = tkinter.Button(rootfr, text = 'Test')
        self.grid(column = 1, row = 1)

    def command_set(self):    
        self.config(command=root.quit)

root = tkinter.Tk()
root.title('Test')

rootfr = tkinter.Frame(root)
rootfr.grid(column = 2, row = 2)

button1 = GuiEl()
button1.command_set()

root.mainloop()

What I want is to create a class, then make an instance - Button. Then I want to use a method on this instance (actually doesn't matter if it's done using the method of class or directly using the parent method) - config, which will modify this instance. What I get is:

Traceback (most recent call last):
  File "class_try.py", line 18, in <module>
    button1.command_set()
  File "class_try.py", line 9, in command_set
    self.config(command=root.quit)
  File "/usr/lib/python3.7/tkinter/__init__.py", line 1485, in configure
    return self._configure('configure', cnf, kw)
  File "/usr/lib/python3.7/tkinter/__init__.py", line 1476, in _configure
    self.tk.call(_flatten((self._w, cmd)) + self._options(cnf))
AttributeError: 'GuiEl' object has no attribute 'tk'

I've been googling for hours but can't deal with it. Kindly asking for your assistance. I know there's no reason to use classes in this situation, but I'm trying to learn how to do this.

You aren't properly initializing your class.

Remove this line which is creating a second button:

self = tkinter.Button(rootfr, text = 'Test')

... and add this line, which properly initializes the current button:

tkinter.Button.__init__(self, text="Test")

Or even better if you're on python3:

super().__init__(text="Test")
