How to get the state of a Checkbutton in python?

I am working on my school project and I am stuck with one thing that is how to get the states of the checkbuttons. I used for loop to create the checkbuttons as there are many checkbuttons. I just don't know how to get the state of the checkbuttons.

Here 'entry1' refers to a list which is needed to input by the user and active_state will store the active state of the checkbuttons.

        active_state=[]
        for i in range (0,len(entry1)):
                    var=IntVar()    
                    check_btn=ttk.Checkbutton(update_record_window,text=entry1[i])
                    check_btn.grid(column=0,row=1+i)
                    active_state.append(var)
        print(active_state)

Please if anybody can tell me what I am doing wrong, it would be very grateful of you. Thanks in advance for the help.

You need to associate the variable created in the loop with the checkbutton. Then it's just a matter of iterating over the variables and getting the values.

var=tk.IntVar()
check_btn=ttk.Checkbutton(..., variable=var)
...
print([var.get() for var in active_state])

Of course, you need to wait until the user has had a chance to interact with the checkbuttons before printing. Usually that means to put the print statement in a function that is called in response to an event.
