Pyodbc does not accept variable from tkinter

[Larz60+]

you need to use prefix tk

def Option_SelectionEvent(event):
    print("do it")
 
optionList = ("Server1","Server2","Server3")
    s = tk.StringVar()
    s.set("a")
    self.om = tk.OptionMenu(master, s, *optionList, command=Option_SelectionEvent)

it all depends on how you import the package
when you write:

import tkinter as tk

your saying import package tkinter, and for my program name tkinter tk
so therefore anywhere tkinter would normally be needed, you use tk instead.

if you import thusly:

from tkinter import *

no prefix is needed, so:

s = StringVar()

works.
