If you read my post carefully, i said: "You need to use
columnconfigure and rowconfigure on ROOT!". Here is the solution;
although, not the correct code you should use because pack is perfect
for this:

## START CODE ##
import tkinter as tk
import tkinter.ttk as ttk

class AppFrame(ttk.Frame):
    def __init__(self, parent, **kwargs):
        super().__init__(parent, **kwargs)
        self.create_widgets()

    def create_widgets(self):
        entry = ttk.Entry(self)
        entry.grid(row=0, column=1, sticky='nsew')
        label = ttk.Label(self, text='Name:')
        label.grid(row=0, column=0, sticky='nsew')

root = tk.Tk()
root.title('Test Application')
root.columnconfigure(0, weight=1)
root.rowconfigure(0, weight=1)
frame = AppFrame(root, borderwidth=15, relief='sunken')
frame.grid(row=0, column=0, sticky='nsew')
root.mainloop()
## END CODE ##

So you prefer to pollute? How bout we just auto import the whole
Python stdlib so you can save a few keystrokes?

Then do "from tkinter.constants import *". I have no complaints
against import all the constants during testing/building, however, you
should be a professional and import only the constants you are going
to use.

Of course not, you never imported them! How could that code possibly
work?

Wah!

Stop whining and act like a professional! You complain about
qualifying constants but you happily type "self" until your fingers
bleed without even a whimper???

Look, either import ONLY the constants you need, or qualify each
constant with a module name/variable; that is the choices available to
a professional. Or, just be lazy and pollute your namespace.

FYI: Lazy coders get what they deserve in the end.
