The cells are opened when clicked and if the user clicks on a cell holding a mine then the user loses. As pixel's value is an integer, all fractions should be rounded down. This point might be a little complicated, but patterns like Observer can simplify this process. We keep doing this until we get the said number of mines. As indicated in other questions: using a position type would make sense, e.g. If nothing happens, download GitHub Desktop and try again.

This version is a little different to the others out there in that it's supposed to start by asking the user how big the grid, then how many mines to insert. Does Python have a string 'contains' substring method? For the other grid, the output should be false: each of the nine 3 3 sub-grids should contain all of the digits from 1 to 9. There was a problem preparing your codespace, please try again. Always use words that explain to readers what the code does through proper variable names. Personally I don't like it when click hides other functionality, I'd put that in a calling function. In general, if you use two different ways to write the exact same thing, the reader will think that you want to convey a message with that. It requires checking for some pre-requisites before flagging the cell for a mine. Some rooms are free (their cost is 0), but that's probably because they are haunted, so all the bots are afraid of them. Find the minimal number of moves required to obtain a strictly increasing sequence from the input. It is guaranteed that you've been riding for less than a day (24 hours). Pass the code through pycodestyle and correct everything it reports. def minesweeper (array): # Vertical iterations for lineIndex in range (len (array)): line = array [lineIndex] outputLine = [] # Horizontal iterations for cellIndex in range (len (line)): # Check cell content if (line [cellIndex] == "O"): northIndex = lineIndex - 1 eastIndex = cellIndex - 1 southIndex = lineIndex + 1 westIndex = cellIndex + 1 This makes it hard to reuse and hard to test.

Variable Naming: line 21 states self.cellsToOpen = w * h - k, but the comment says # Create a new board with size w x h, and the caller is MineBoard(w, h, m). Why is "1000000000000000 in range(1000000000000001)" so fast in Python 3? The two equal numbers are a and c. The third number (b) equals 7, which is the answer. Asking for help, clarification, or responding to other answers. I have written this code in Python 3: def arrayChange (inputArray): original = inputArray [:] count = 0 if len (set (inputArray)) == 1: return ( (len (inputArray)-1)**2 + (len . Code Comments: Comments, if used at all, should be a "why you're doing it this way" and not a "how you're doing this". After storing the input, we have to do some sanity checks, for the smooth functioning of the game. [input] array.array.boolean matrix For classes, be aware of what variables which are internal/private, and place an underscore _ before them. This way, the main entry point will only be automatically executed if the module is run as a script, but not if it is imported: Since you intend to run this as a script, it should have a shebang line, something like this: Note: In order to make this answer useful for future readers, I have mostly assumed Python 3.10, which is about to be released soon.
