Python - How to assign items from dictionary's set to Option Menu?

[Aleks_Retr0]

I just can't figure out how to create an option menu (drop-down list or combobox) with items from the set in the dictionary. I have various sets, but I'm only interested in the "Individuals" set at the moment.

The instructions that I found on the Internet tell how to create an option menu with already existing items in the list or set, but my set is initially empty, and gradually fills up when the user enters a new name in this set.

I would like to know how to create an option menu that will display all the names that are in the "Individuals" set.

 

The final result should look like:

Please select an individual: Name1

________________________ Name2

________________________ Name3 etc.

My current option menu just displays all the sets that are in the dictionary, and not the names in the "Individuals" Set.

My code:

from tkinter import *
from tkinter import messagebox
import tkinter.ttk as ttk

# This code is a simplified version of a full program code. In the original program, there is not only a list
# of individuals, but also lists of team1, team2 ... team4.
# However, now I am only interested in the problems associated with individual list,
# and I cut out all the part of the code related to team.


class CollegeApp(Tk):
    def __init__(self):
        Tk.__init__(self)
        container = ttk.Frame(self)
        container.pack(side="top", fill="both", expand=True)
        self.frames = {}
        for F in (IndividPage, listCheckPage, counterPage):
            frame = F(container, self)
            self.frames[F] = frame
            frame.grid(row=0, column=0, sticky="nsew")
        self.show_frame(IndividPage)
        self.lift()

    def show_frame(self, cont):
        frame = self.frames[cont]
        frame.tkraise()


# In this  class I have created a window with entry widget to input name of individual and save it in
# eponymous set "Individual"

class IndividPage(ttk.Frame):

    def __init__(self, parent, controller):

        self.TeamName.set("Individual")

                            command=self.confirm)

# Instead of that I want the combobox will show all the names that were entered in the "Individuals" set.
# I would also like to point out that the same process will be used for the sets of team1, team2 etc.

Can't look in-depth at the moment, but from a quick glance, you feed it the entire dictionary, so it's only natural all the entries in the dictionary show up no? If you want it to only show entries in "Individuals" you'll need to pass only that set.

@tikker Yes, but the problem is that if I will change 

*teams

to 

*Individual

It doesn't work, PyCharm just underline it with red line

It probably  underliens it because Individual doesn't exist as a variable? It would be teams['Individual']
