The state of a cell on a board is encoded with a single integer, which combines the following information: This results in complicated code to check those properties, numerous magic numbers, and a lot of crevices where bugs can creep in. Given n and firstNumber, find the number which is written in the radially opposite position to firstNumber. Object Oriented Programming with Python - Code a Minesweeper Game then count the number of Xs in the merged tuples: This runs roughly 5x faster than the index/offset based solution. These items are something you should be aware of when writing Python code. Construct a square matrix with a size N N containing integers from 1 to N * N in a spiral order, starting from top-left and in clockwise direction. Correct variable names consist only of Latin letters, digits and underscores and they can't start with a digit. . Consider integer numbers from 0 to n - 1 written down along the circle in such a way that the distance between any two neighbouring numbers is equal (note that (0 and n - 1 are neighbouring, too). The code is compatible with PyQt5 or PySide2 (Qt for Python), the only thing that changes is the imports and signal signature (see later).

The objective is to fill a 9 9 grid with digits so that each column, each row, and each of the nine 3 3 sub-grids that compose the grid contains all of the digits from 1 to 9. The complete move therefore looks like the letter L. Check out the image below to see all valid moves for a knight piece that is placed on one of the central squares. : Comments in the code explaining what the code does when the code expresses this already, Classes exposing private attributes as public, Mixing game logic with board logic (and instantiating the board as.

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. A character which is either a digit or not. Instead of looping unnecessarily over out-of-bound cells, try instead adjusting the range boundaries: This is just a spur-of-the-moment idea, but you could implement __getitem__ for the MineBoard class. We need to set up the positions of the mines randomly, so that the player might not predict their positions. Given an array of integers, find the maximal absolute difference between any two of its adjacent elements. After some thought, your first guess is that each consecutive 8 bits of the code stand for the character with the corresponding extended ASCII code. Also, I have them set to pretty aggressive settings, which can sometimes be annoying and overwhelming if you work with code that you haven't freshly written yourself.
