i keep getting the error AttributeError :
'_tkinter.tkapp' object has no attribute 'getitems'
i think this is because the subroutines cannot communicate with each other i have tried assigning get_items as a global variable with no results. i am trying to make a button that collects the entries in the GUI enters them into a database with Sql Lite for an inventory system for a car dealership.
from tkinter import*
import sqlite3
conn = sqlite3.connect("E:\computing project\database of cars.db")
c=conn.cursor()
class Database:

I see two mistakes:
First: you define method get_items (with _ in name) but you use command=self.getitems (without _ in name)
self.b = Button(command=self.get_items)
Second: you have arguments in wrong order is
__init__(kwargs, self, master=None, *args)
so it assigns class instance to variabla kwargs instead of self and it assigns root to self and later it has problem to find self.get_items because it means root.get_items
kwargs should be at the end, and self at the beginning
__init__(self, master=None, *args, **kwargs)
