Answer

You need to invoke Tk’s mainloop. Add tk.mainloop() at the end of your code. Besides that, I suggest you use import tkinter as tk (in which case you would have to rename your variable to something else (suggestion: root is kind of idiomatic)) instead of from tkinter import *, since you don’t know what names that imports. It can replace names you imported earlier, and it makes it very difficult to see where names in your program are supposed to come from.
