                self.remove_widget(self)
        # Задание способа записи задания в файл с списком
        for f, d in sorted(dic_tasks.items(), key=lambda x: x[1]):
            fd = f.decode('u8') + '\n' + (datetime.fromtimestamp(d).strftime('%Y-%m-%d'))
            self.btn = Button(text=fd, size_hint_y=None, height=dp(40), on_press = del_winget)
