【问题描述】：

我不断收到错误 AttributeError ：

'_tkinter.tkapp' 对象没有属性 'getitems'

我认为这是因为子例程无法相互通信我尝试将 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，将它们输入到带有Sql Lite 的数据库中，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.place(x=0,y=100)

root = Tk()
b = Database(root)
frame = Frame(root,width=1920,height=1080)
root.geometry("1920x1080")
root.title("add to database")
root.configure(background="#b7b7e5")
root.mainloop()

【参考方案1】：

我看到两个错误：

首先：您定义了方法get_items（名称中带有_）但您使用command=self.getitems（名称中没有_）

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

第二：你的论点顺序错误是

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

因此它将类实例分配给变量kwargs 而不是self，并将root 分配给self，后来它很难找到self.get_items，因为它意味着root.get_items

kwargs 应该在结尾，self 在开头

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