Place two labelframes next to each other in Tkinter

Question

I would like to display two labelframes next to each other like in the following picture Picture1. Do you have any idea on how to do it?

When I try the labelframe don't stay in place and just resized to text into it.

This is what I want but with txt center in the labelframes

import tkinter as tk
from tkinter import ttk

root = tk.Tk()
root.geometry('600x200')
style = ttk.Style(root)
root.tk.call('source', 'azure dark.tcl')
style.theme_use('azure')

lf1 = ttk.Labelframe(root, text='Labeltxt1', width=300,height=100)
lf1.grid(row=0,column=0)
lf2 = ttk.Labelframe(root, text='Labeltxt2', width=300,height=100)
lf2.grid(row=0,column=1)

root.mainloop()

And this is what I get :

import tkinter as tk
from tkinter import ttk

root = tk.Tk()
root.geometry('600x200')
style = ttk.Style(root)
root.tk.call('source', 'azure dark.tcl')
style.theme_use('azure')

lf1 = ttk.Labelframe(root, text='Labeltxt1', width=300,height=100)
lf1.grid(row=0,column=0)
lf2 = ttk.Labelframe(root, text='Labeltxt2', width=300,height=100)
lf2.grid(row=0,column=1)

lb1= ttk.Label(lf1, text='txt1')
lb1.pack()
lb2= ttk.Label(lf2, text='txt2')
lb2.pack()

root.mainloop()

The labelframes don't fill the width of the window.

Hope that I've been clear enough. Thanks for the help.

You need to tell the layout manager that the two Labelframe fill all the available space by using root.rowconfigure() and root.columnconfigure(). Also need to specify sticky='nsew' in .grid(...). In this case, you don't need to specify the width and height options of the Labelframe.

...
root.rowconfigure(0, weight=1)
root.columnconfigure((0,1), weight=1)

lf1 = ttk.Labelframe(root, text='Labeltxt1')
lf1.grid(row=0, column=0, sticky='nsew')
lf2 = ttk.Labelframe(root, text='Labeltxt2')
lf2.grid(row=0, column=1, sticky='nsew')
