Tkinter - geometry managers (place)

https://realpython.com/python-gui-tkinter/

INTRODUCTION

The geometry manager .place() can be used to control the precise location that a widget should occupy in a window or Frame.

.place() is not used often, because it has two main drawbacks:
(1) layout can be difficult to manage with .place(),
(2) layouts created with .place() are not responsive.

import tkinter as tk

root = tk.Tk()

frame = tk.Frame(root, width=300, height=300, bg="blue")
frame.grid()   # .grid() is here

label1 = tk.Label(frame, text="I'm at (0, 0)", bg="red")
label1.place(x=0, y=0)   # top left, in pixels

label2 = tk.Label(frame, text="I'm at (50, 100)", bg="yellow")
label2.place(x=50, y=100)   # in pixels from top left

root.mainloop()   # run the tkinter event loop
