Getting an entry widget's content into a separate function

For very personal reasons, I program procedurally. Let's say I create a Tkinter window with an entry widget and a button widget in one function and the button triggers another function which is supposed to process the entry widget's content.

So far I have only managed to get it working with StringVar and global variables.

Can I avoid classes AND global variables?

#!/usr/bin/python

try:
    # Python2
    import Tkinter as tk
except ImportError:
    # Python3
    import tkinter as tk

import os


def output():
    global gamename
    print("The widget's value is: " + gamename.get())

def newGame():
    global gamename

    win1 = tk.Toplevel()   

    e = tk.Entry(win1, textvariable = gamename)
    e.place(x = 0, y = 30, width=200, height=30)     
    outp = tk.Button(win1, text="Print", command=output)
    outp.place(x = 0, y = 110, width=200, height=30)

    win1.mainloop()

root = tk.Tk()
gamename = tk.StringVar()

newGame()
tk.mainloop()

No.

There's simply no good reason to not use classes when writing large programs in python. If you're writing small programs, there's nothing wrong with using globals.
