.get() not retrieving value?

[menator01]

Here is an example using a callback function

import tkinter as tk
from tkinter import ttk

# Function to print value. Using combo.get() to get the value
def callback(event):
    label['text'] = f'Selected: {combo.get()}'

root = tk.Tk()
root.geometry('400x200+300+300')

# Label to display text
label = tk.Label(root, anchor='w')
label.pack(fill='x',padx=10)

# Some values to populate the combobox
values = [(f'Value {i}') for i in range(11)]

# Define the combobox
combo = ttk.Combobox(root, state='readonly')
combo['values'] = values
combo.current(0)
combo.pack(pady=5)

# Bind the combobox and set the function callback
combo.bind('<<ComboboxSelected>>', callback)

# Print starting value for label
label['text'] = callback(event=None)

root.mainloop()
