Can anyone please tell me, why I get the error 'NoneType' object has no attribute 'get'?

import tkinter as tk

from tkinter import messagebox



class App(tk.Tk):

    def __init__(self):

        tk.Tk.__init__(self)

        self.lab1 = tk.Label(text="Abfahrtsort").grid(row=0, column=0, sticky="w")

        self.start = tk.Entry(self).grid(row=0, column=1)

        self.lab2 = tk.Label(text="Zielort").grid(row=1, column=0, sticky="w")

        self.end = tk.Entry(self).grid(row=1, column=1)

        self.button = tk.Button(self, text="Anzeigen", command=self.on_button).grid(row=2, column=1)



    def on_button(self):

        messagebox.showinfo(self.entry.get())

This question has been asked before and already has an answer. If those answers do not fully address your question, please ask a new question.

Change self.entry.get() to self.end.get(). You are trying to use get() on a non-existent self.entry. Seeing that you have defined your entry field as self.end you need to change your messagebox statement to reflect the same. On top of that you need to use grid() on a new line separate from where you define your entry field.

You have two issues here in your code. The 1st one is your grid() statement.

Change these:

self.start = tk.Entry(self).grid(row=0, column=1)

self.end = tk.Entry(self).grid(row=1, column=1)

To this:

self.start = tk.Entry(self)

self.start.grid(row=0, column=1)

and this:

self.end = tk.Entry(self)

self.end.grid(row=1, column=1)

The 2nd is your messagebox statement.

Change this:

messagebox.showinfo(self.entry.get())

To this:

messagebox.showinfo(self.start.get())

Or this depending on what entry you are trying to access:

messagebox.showinfo(self.end.get())

You will also need to correct the indention of your self.end and self.button to be inline with everything else in your __init__ method.
