As we can see clearly, any number on the grid denotes the number of mines present in the neighbouring eight cells. The variables are the board squares, which each contain either a mine or a constant between 0 and 8. over 12.5 years). This method uses higher level functions to detect the state of a position, but then uses += 1 to set the state. The building is represented by a rectangular matrix of rooms, each cell containing an integer - the price of the room. So, for example, there is an obvious way that looks like it should work, but you tried it and it didn't work for a non-obvious reason.

It looks like you are missing an abstraction, probably something like a Cell (which could be a namedtuple or a dataclass). Many Git commands accept both tag and branch names, so creating this branch may cause unexpected behavior. When I save your code into a file and open the file in my editor, I get a whopping, Now, to be fair, a lot of these are duplicates, because as I mentioned, I have multiple linters and analyzers set up. You might also get some constant-factor time wins by iterating over the lists with enumerate instead of doing the for index in range() thing, and minimizing the number of extra variables you allocate. It took me a few seconds to understand that it required an upper-case F to correctly flag a tile. Therefore, Minesweeper has a provision of using flag to mark the cells, which we know contains a mine.
