getting error AttributeError: '_tkinter.tkapp' object has no attribute 'getitems'

Question

我一直收到错误 AttributeError :

'_tkinter.tkapp' object has no attribute 'getitems'

我认为这是因为子例程无法相互通信我已经尝试将 get_items 分配为全局变量但没有结果。我正在尝试制作一个按钮，用于收集 GUI 中的条目，将它们输入带有 Sql Lite 的数据库，用于汽车经销商的库存系统。

from tkinter import* 
import sqlite3
conn = sqlite3.connect("E:\computing project\database of cars.db")
c=conn.cursor()



class Database:
    def __init__ ( kwargs , self, master=None ,*args):
        self.master = master
        self.heading = Label(master , text = "add to the database ", font=("ariel 35 bold") )
        self.heading.place (x=250 , y=0)

        self.name= Label(master, text= "enter product name", font=("arial 18 bold"))
        self.name.place(x=0,y=50)



        self.make_1=  Label(master , text = "enter car make ", font=("ariel 18 bold"))
        self.make_1.place(x=0,y=100)

Answer 1

我看到两个错误：

首先： 你定义了方法 get_items（名称中有 _）但是你使用了 command=self.getitems（没有 _在名字中）

 self.b = Button(command=self.get_items)

其次： 你的参数顺序错误是

__init__(kwargs, self, master=None, *args)

所以它将 class 实例分配给 variabla kwargs 而不是 self 并将 root 分配给 self 然后它有问题找到 self.get_items 因为它意味着 root.get_items

kwargs应该在最后，self在开头

__init__(self, master=None, *args, **kwargs)
