Как передать значение Checkbutton

Для получения значения его можно сохранить в переменную check_val.

check_val = IntVar()
sun_m_addw = Checkbutton(text = "Sunday morning" , variable=check_val)

Несколько более упрощенный пример для демонстрации.

from tkinter import *
 
root = Tk()
root.geometry("100x100")
 
check_val = IntVar()
 
btn = Checkbutton(text="test", variable=check_val)
btn.pack()
 
lb = Label(textvariable=check_val)
lb.place(relx=0.1, rely=0.1,)

root.mainloop()

К сожалению IntVar() принимает только значения типа integer , при попытке присвоить 'yes' или 'no' , выдаёт что-то вроде

Exception in Tkinter callback Traceback (most recent call last): File "C:\Programs\Python38-32\lib\tkinter_init_.py", line 535, in get return self._tk.getint(value) _tkinter.TclError: expected integer but got "yes"

Я нашёл вот такое вот решение :

from tkinter import *
destroy_obj = []
def CheckChange(name):
    if name.get() == 1 : x = "yes"
    else : x = "no"
    return x 
def Destroy_object():
    for x in destroy_obj:
        x.destroy()
