Cancel user window sizing

Question

After a user manually resizes a tkinter window, it no longer shrinks to fit.

What tkinter command would revert it back to the 'shrink to fit' behavior?

I had a hard time remembering how to this, as it has been so long. In Tcl use:

wm geometry . {}

Can one of the python people edit the answer and translate this for tkinter, thanks.

@Atlas435 wrote this code for tkinter:

import tkinter as tk

root=tk.Tk()

def normal():
    root.geometry('')

b = tk.Button(root,text='shrink', command=normal)
b.pack()

root.mainloop()
