[Tkinter] Unable to create checkbox and select at run time

[tej7gandhi]

Hello All,

I am facing some challenge with my user interface:

def PopUp():
        pop = Tk()
        count =output1.split()

        for  i in range(0,len(count)):
                var=[]

                l=Checkbutton(pop,text=output1.split()[i],variable=var.append(i)).grid(row=i+1,sticky=W)

This will print output as:

Output:
x  ABC
x  CDE
x  DEF

Depending upon how many values are there in count

Now when user selects ABC and DEF that is checkbox 1 and 3,wanted to take these values and perform certain operations or all three checkbox.
so wanted to understand how can store the values that user selected and then utilize them further.
