Python can evaluate strings including numbers and letters
>>> '0'<'1'<'2'<'3'<'4'<'5'<'6'<'7'<'8'<'9'<'X' True
As you iterate through the grid the cavities are marked with the 'X' where all the adjacent cells are less than. For example
'X'
1111 1911 1911 1111
returns with no cavities as 9 and 9 are equal.
9
If we replace with an X it is because the surrounding cells evaluate as less than.
X
So if 9 > 8 so too is X > 8 so the relationship between the cells is maintained and there is no need to check for X
9 > 8
X > 8
