我的 tkinter 输入框正在打印 .!entry 而不是输入的内容

Question

from tkinter import *
def _name_():
              businessname=entry_bn
              print(businessname)
edit_bar=Tk()
name=Label(edit_bar,text="Name:").grid(row=0)
entry_bn=Entry(edit_bar)
entry_bn.grid(row=0,column=1)
submit=Button(edit_bar,text="Submit",command=_name_).grid(row=1,column=2)

每当我按下提交按钮时，我都会打印出 .!entry，而不是输入框中输入的内容。有任何想法吗？谢谢

Question: i get .!entry printed out, instead of what is entered into the Entry

参考:

Tkinter.Entry.get-method

Gets the current contents of the entry field. Returns the widget contents, as a string.

import tkinter as tk


class App(tk.Tk):
    def __init__(self):
        super().__init__()

        tk.Label(self, text="Name:").grid(row=0, column=0)
        self.entry = tk.Entry(self)
        self.entry.grid(row=0, column=1)

        btn = tk.Button(self, text="Submit", command=self.on_submit)
        btn.grid(row=2, column=0, columnspan=2, sticky='ew')

    def on_submit(self):
        print('Name: {}'.format(self.entry.get()))


if __name__ == "__main__":
    App().mainloop()
