How to check listbox tkinter?

Question

Python

Hello.
Started disassembling Tkinter, decided to write a small program, ran into a problem. I don't know how to check a SPECIFIC listbox.
Found a universal method:
root.bind('<<ListboxSelect>>', check)
Well, the output of the index:

def check(event):
    print event.widget.curselection()

I explain. There will be several listboxes, you need to check each one separately.
Thank you in advance for your help ;)
