Tkinter checkbutton.select() not working on Checkbutton (Python 3)

Question

I am writing a program which reads data form a file, and adjust the settings accordingly. This is how I created the checkbutton:

should_auto = BooleanVar()    
autodetect = Checkbutton(root, text="Autodetect", var=should_auto, onvalue = True, offvalue = False, command=toggle_delay)
autodetect.grid(row=0, column=2, padx=7, pady=5, sticky=W)

I then try to "check" it using:

autodetect.select()

but this returns following error:

Traceback (most recent call last):
  File "C:\Users\CedBook\Documents\GitHub\live-image-desktop-background\src\GUI.py", line 110, in <module>
    autodetect.select()
AttributeError: 'Checkbutton' object has no attribute 'select'

I have already also tried using autodetect.set(True), but then i get almost the same error, but Checkbutton object has no attribute 'set' I saw .select() on effbot.org, but maybe that is not for python 3?

use autodetect.set(1)?

Can you set the value of the boolean instead?

should_auto.set(True)

should update the checkbox that relies on it.

autodtect.set(1) might have worked, but that was the button, not the variable. Thanks anyway both of you.

@Ath.Bar. it sounds like you're trying to set the value of the checkbutton not the variable backing it, See the OP where should_auto is a BooleanVar and is passed to the Checkbutton as the var keyword.
