Getting "object has no attribute". (First time using class)

Question

I'm trying to create a frame with 3 frames inside using class (to add more frames in the future with ui button).First time I'm using class. It gives me error, and I can't find in google what is the problem. It seems can't access variables stored in class object after creation, but ui builds correctly.(Error after pressing button)

from tkinter import *

window = Tk()

names = [["123","456","789"]]

window.title("123")
window.geometry('400x250')
window.resizable(False, False)

def savebuttonfunc():
    for i in names:
        if type(i) != 'list':
            i = []
        i[0] = title.entry.get()
        i[1] = description.entry.get()
        i[2] = voicechat.entry.get()


top = Frame(window)
top.grid(row=0)
titletop = Label(top, text="Top")
titletop.grid(column=0, row=0, padx=(5, 10))
savebutton = Button(top, text="Save", command = savebuttonfunc)
savebutton.grid(column=3, row=0, padx=(5, 10))

eb = Frame(window)
eb.grid(row=1)

class Entries:
    def __init__(self, column, width, text, id):
        self = Frame(eb)
        self.grid(row=1,column=column, padx=(5, 10))
        self.string_var = StringVar()
        self.entry = Entry(self, textvariable=self.string_var, width=width)
        self.entry.grid(row=1)
        if not names[0][id]:
            self.string_var.set('123')
        self.string_var.set(names[0][id])
        self.txt = Label(self, text=text)
        self.txt.grid(row=0)

title = Entries(1,10, 'Title', 0)
description = Entries(2,25, 'Description', 1)
voicechat = Entries(3,7, 'VoiceChat', 2)

window.mainloop()

Exception in Tkinter callback

`self = ...` in your init is very wrong. You shouldn't rebind that name in your methods. I'm not sure what you're trying to do. — Andras Deak -- Слава Україні, May 02 '21 at 11:11
Also read [this](https://stackoverflow.com/questions/1101750/tkinter-attributeerror-nonetype-object-has-no-attribute-attribute-name) and look at what you used: `self.entry = Entry(...).grid(...)` — TheLizzard, May 02 '21 at 11:17
I presume "first time using class" in the question's title means this is your first time writing your own class. If this is the case, you'd benefit a lot from reading a good tutorial first. — Andras Deak -- Слава Україні, May 02 '21 at 11:17
@AndrasDeak How do I create frame in variable which calls this class in other way? I have tried self.frame = Frame(eb) , and put other things into self.frame, but result the same — Максим Филоненко, May 02 '21 at 11:19
@TheLizzard Yeah, thank you. I checked, and changed everywhere separately. But result is the same. — Максим Филоненко, May 02 '21 at 11:27
If you replaced `self = Frame(eb)` with `self.frame = Frame(eb)` you should not see the same result. Can you update your code with this? — Andras Deak -- Слава Україні, May 02 '21 at 11:49
@AndrasDeak Thank you, problem solved. I have tried with self.frame before and it's didn't worked, but for now it's working! Maybe i fixed something when i was preparing code for question.) — Максим Филоненко, May 02 '21 at 12:43
