Hi I am trying to loop through a child widgets of a frame and store the values of the entry and checkbutton widgets into a list. It seems to work for the entrys but the checkbutton I get an error. If you could help that would be much appreciated thanks.

for child in top.winfo_children():        
            if child.winfo_class() == 'Entry':
                mylist.append(child.get())
            elif child.winfo_class() == 'Checkbutton':            
                mylist.append(child.get())

I am getting an error here:

mylist.append(child.get())

The error is :

    mylist.append(child.get())
AttributeError: 'Checkbutton' object has no attribute 'get'

You need to use `variable.get()`. – jizhihaoSAMA May 14 '20 at 05:25
You need to associate each `Checkbutton` to its own tkinter variable (`StringVar`, `IntVar`, etc) and use its variable to get the checkbutton checked state. – acw1668 May 14 '20 at 05:33
how would i do that if I am creating a row full of checkbuttons on the fly with for loop? – inexperiencecoder May 14 '20 at 05:54
the check buttons look like "Checkbutton(frame, text="").grid(row=j, column=k)" – inexperiencecoder May 14 '20 at 06:00

@inexp ***how would i do that .. checkbuttons ... with for loop?***: Follow this approach [Correctly extend a tkinter widget](https://stackoverflow.com/a/60322108/7414759) extend will a `get()` method. – stovfl May 14 '20 at 10:17
