Tkinter checkbox value

[menator01]

Here is something I been playing around with.

#! /usr/bin/env python3.8
'''Docstring'''

import tkinter as tk
from functools import partial

class CheckBoxes:
    '''Docstring'''

    def __init__(self, master):
        self.master = master
        self.master.columnconfigure(0, weight=1)

        self.mainframe = tk.Frame(self.master)
        self.mainframe.grid(column=0, row=0, sticky='news')
        self.mainframe.grid_columnconfigure(0, weight=3)

        self.chkbox_frame = tk.Frame(self.mainframe, border=5, relief='ridge')
        self.chkbox_frame.grid(column=0, row=0, sticky='new')

        self.textframe = tk.Frame(self.mainframe, border=5, relief='ridge', height=73)
        self.textframe.grid(column=0, row=1, sticky='new')

        self.btnframe = tk.Frame(self.mainframe, border=5, relief='ridge')
        self.btnframe.grid(column=0, row=2, sticky='new')

        self.myvars = []

        self.chkboxes()
        self.btnbox()

    def chkboxes(self):
        self.boxes = ['Checkbox 1', 'Checkbox 2', 'Checkbox 3']
        i = 0
        for self.box in self.boxes:
            myvar = tk.StringVar()
            self.chkbox = tk.Checkbutton(self.chkbox_frame, text=self.box, variable=myvar, onvalue='Checked', offvalue='Un-Checked')
            self.chkbox.deselect()
            self.chkbox.grid(column=0, row=i)
            i += 1
            self.myvars.append(myvar)

    def print_frame(self, myvars):

            label = tk.Label(self.textframe, text=f'{self.boxes[i]} -> {myvar.get()}')
            label.grid(column=0, row=i, sticky='w')
            i += 1

    def btnbox(self):
        self.button = tk.Button(self.btnframe, text='Click Me', \
        command=partial(self.print_frame, self.myvars))
        self.button.grid(column=0, row=0)

        self.myvars=''
        self.clear_btn = tk.Button(self.btnframe, text='Clear', \
        command=partial(self.print_frame, self.myvars))
        self.clear_btn.grid(column=1, row=0, padx=20)


def main():
    root = tk.Tk()
    root.title('Checkboxes')
    root.geometry('400x200+50+50')
    CheckBoxes(root)
    root.mainloop()
