Generally the code shows a consistent style, so in that regard I think it looks good. 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. It's still O(n) time with respect to array, though; it's not really possible to improve on that. 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.

In this article, we will be going through the steps of creating our own terminal-based Minesweeper using Python Language. 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. For each cell in the grid, we have to check all adjacent neighbours whether there is a mine present or not. It could access Cell objects and -- when passed slices --- could even return an iterable over the Cells. However, it is also rather dangerous. The same applies to the game loop itself, it also has distinct steps. Suitable implementation of __getitem__ left as an exercise for the reader. one with mines (and mine counts, for convenience) and one layer that shows if the position has been revealed or flagged.

Read on for a walkthrough of how the code works. There is a requirement to check for completion of the game, each time a move is made. It looks like you are missing an abstraction, probably something like a Cell (which could be a namedtuple or a dataclass). 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. // The arrays are equal, no need to swap any elements. Since he likes to make things perfect, he wants to arrange them from smallest to largest so that each statue will be bigger than the previous one exactly by 1. Your code is all bunched up together. @KennyOstrom I don't see an issue with it. Thank you in advance. Thank you for taking your time ! I'd have to print out the board to understand printLayout fully, but that's OK. (I've taken the liberty of converting all identifiers to PEP8 style.). Oh well, a bit of unfairness never hurt :).

You wrote that you're going for coding interviews, so I'll focus on various aspects that will be looked at by interviewers rather than pieces of code which other respondents already have. It can be done by 'import os' at the start of the program. You tell the function when to do something, not ask it if it's ready to do it/if it has it. Does Python have a ternary conditional operator? A media access control address (MAC address) is a unique identifier assigned to network interfaces for communications on the physical network segment. // You're strong enough to take both of the items with you. You can pass any iterable to the list constructor to create a list: You import pdb but never use it. Some rooms are free (their cost is 0), but that's probably because they are haunted, so all the bots are afraid of them. Each day a plant is growing by upSpeed meters.
