'''In the popular Minesweeper game you have a board with some mines and those cells that don't contain a mine have a number in it that indicates the total number of mines in the neighboring cells. Then a nested loop on each position can go through the offsets to add 1 to the 'zero' cells when the neighbouring position is in range of the board and contains an "X": If you want to avoid messing with indexes and offsets, you can prepare 8 shifted copies of the board (one per direction) and use zip() to combine them into a tuple of neighbours for each position.

At least I presume it is a margin of sorts. An example of what I mean is the print_layout method. You fixed the bad borders, but OP had a simple if, where you use exception handling as "regular" code logic. Mostly, comments should not exist: The only acceptable thing for a comment is to explain why the code does something in a specific non-obvious way. I am not a big fan of mixing I/O and computation. // You can't take both items, but you can take any of them. Rather than doing that, the set_alarm(self, hour, minute) function would spawn a thread which waits for hour/minute and then activates a call-back to the activate_alarm(self) function.
