tkinter checkbutton if checked

[joe_momma]

one major issue with your code is it's not a class. here's a checkbox

import tkinter as tk
 
 
class MainFrame(tk.Frame):
 
    def __init__(self, *args, **kwargs):
        super().__init__(*args, **kwargs)
        self.vars=[]
        self.checkbuttons = {'pizza': tk.IntVar(),
                             'salad': tk.IntVar(),
                             'coffee': tk.IntVar()}
         
        for key, value in self.checkbuttons.items():
            ctrl = tk.Checkbutton(self, text=key, variable=value)
            ctrl.pack()
            self.vars.append(value)
         
        self.button = tk.Button(self, text='Checkbutton values',
                                command=self.on_button)
        
        self.button.pack(pady=5,padx=10)
        self.pack()
 
    def on_button(self):
        res= []
        for key, val in self.checkbuttons.items():
           select= val.get()
           if select:
                print(f'you selected {key}')
        
 
 
if __name__ == '__main__':
    app = tk.Tk()
    main_frame = MainFrame()
    app.mainloop()
