[Python] Changing button's look by state; Only works while debugging

For some background, I'm displaying my button as an image. What I want to change the look of my button when it's clicked and keep it as that new look until it is clicked again. Here's what I have so far:

from tkinter import *
from tkinter import ttk

def TestLogic():
print(testBtn["state"])
if testBtn["state"] == "normal":
stgImg = PhotoImage(file="test1.png")
testBtn.configure(image=stgImg)
testBtn.image = stgImg
testBtn.configure(state="active")
elif testBtn["state"] == "active":
stgImg = PhotoImage(file="test.png")
testBtn.configure(image=stgImg)
testBtn.image = stgImg
testBtn.configure(state="normal")

root = Tk()

root.geometry('600x600')

stgImg = PhotoImage(file="test.png")
testBtn=ttk.Button(root, text="TEST", image = stgImg, command=TestLogic)
testBtn.pack(anchor="center")
root.mainloop()


The problem is that without the print statement the code doesn't work, however, it works just fine with the print statement. I want to know why, how to fix this issue so I don't have to have the print statement, and possibly some ideas on how to improve this.
