[Tkinter] Hide clicked buttons

[Rubberduck]

Hi Yoriz

Awesome. Thanks a lot for your excellent response and also for the good input about the from tkinter import *. Your code works absolutely perfect and fulfils my needs.

Best Wishes,
Rubberduck

Don't use from tkinter import * see Namespace flooding with * imports
If you don't want the widget anymore you can destroy it.

import tkinter as tk
import csv


def yield_csv(file_path):
    with open(file_path, 'r') as csv_file:
        csv_reader = csv.reader(csv_file, delimiter=',')
        for line in csv_reader:
            yield line


class App(tk.Tk):
    def __init__(self, *args, **kwargs):
        super().__init__(*args, **kwargs)
        self.title('Fahrzeugkontrolle')
        self.geometry('500x1000')
        self.string_var = tk.StringVar()
        self.string_var.set("prove")
        self.r_btns = {}

        csv_ = yield_csv('PostDummy.csv')
        next(csv_)
        for line in csv_:
            value = f'{line[3]}, {line[1]}'
            r_btn = tk.Radiobutton(self, text=line[3],
                                   variable=self.string_var, value=value)
            r_btn.pack(anchor=tk.W)
            self.r_btns[value] = r_btn

        myLabel = tk.Label(self, text=self.string_var.get())
        myLabel.pack()

        myButton = tk.Button(self, text="OK", command=self.on_btn)
        myButton.pack()

    def on_btn(self):
        value = self.string_var.get()
        myLabel = tk.Label(self, text=value)
        myLabel.pack()
        self.r_btns[value].destroy()


if __name__ == '__main__':
    app = App()
    app.mainloop()
