You want to set the max height to 0.  I know this is counter-
intuitive. Both values must be a number or None, not mixed.  So to do
what you want to do it would be this:

some_window.wm_minsize(width=min_width, height=min_height)
some_window.wm_maxsize(width=max_width, height=0)

Note that these numbers are in pixels if you're using .pack() and
according to the docs it's in grid coordinates if you're using .grid()

Good luck!
Roger.
