Problème récupération ligne liste tkinter

Bonjour, je cherche à récupérer la ligne sélectionnée dans ma liste. 
Voici le code morceau de code en question. 

Pour expliquer avant, quand je clique sur une ligne, une erreur apparait.
 

def get_list1():
    index = list1.curselection()
    print(index)
    pass


list1.bind("<<ListboxSelect>>", get_list1)

l'erreur que me sort le programme est la suivante : 

Exception in Tkinter callback
Traceback (most recent call last):
  File "C:\Python310\lib\tkinter\__init__.py", line 1921, in __call__
    return self.func(*args)
TypeError: get_list1() takes 0 positional arguments but 1 was given

Si vous souhaitez le code entier pour l'exécuter, le voici :
