'Tuple' Object is not callable: Module Tkinter, Object Listbox with method curselection. Language: Python

Question

Hello Dear Programmers.

I have a "Tuple Object is not callable" Errror and I need your help.

File "D:\Miniconda3\envs\ml_env\lib\tkinter\__init__.py", line 1705, in __call__
return self.func(*args)
File "D:\Desktop\Gestion de projet mayadigital\inter_admin.py", line 242, in valider_suppression
for i in self.employes():
TypeError: 'tuple' object is not callable

I am creating a small software linked to a database. One of the options allows the admin to delete one or multiple users.

To do this I created a Listbox inside a Tkinter Instance. After the admin selected the users to delete, I want to display the list of theses users for confirmation.

This is where I have my problem:

I need to know which are the item clicked on the Listbox, so I use this method:

self.employes=self.liste_employes.curselection()

But when I want to use self.employes thanks to the following code, I get the error.

 for i in self.employes():
        self.employes_a_supprimer.insert(i, rows[i][1]+' '+rows[i][2])
    self.employes_a_supprimer.pack()

This is an extract of my code:

Yes, this is a french code;)

Supprimer=Delete

Valider_Suppression=Confirm_suppression

I hope I've made myself clear enough to be understood

Thanks a lot for the future answers on my post.

Answer 1

The answer is an error in my code I could not see, thanks to @bryan-oakley for his help.

The right piece of code is:

for i in self.employes: #Without parenthesis
        self.employes_a_supprimer.insert(i, rows[i][1]+' '+rows[i][2])
    self.employes_a_supprimer.pack()

Problem solved !
