Found this while reverting a data entry form to database values (ie:
Undo), all my fields became "None". Set changes None to a string,
creating with value= doesn't.
Seems inconsistent, is this intentional or to be expected?

#!/usr/bin/env python3
from tkinter import *
from tkinter import ttk
import tkinter.font as tkFont
root = Tk()
print("Creating a stringvar")
derp=StringVar(value=None)
print("Derp was created with value of None, it's value is
'{}'.".format(derp.get()))
print("Now setting derp to None again")
derp.set(None)
print("Derp was set to None, it's value is '{}'.".format(derp.get()))
assert derp.get() == ''
