#check web for more info on grid or pack manager
#such as:
#https://www.python-course.eu/tkinter_layout_management.php

#Warning: Never mix grid and pack in the same master window!
#this app does use both in two separate frames to demo both -
#don't actually do this! tkinter will crash if both conflict.
#choose either pack or grid and stick to it!
