For one, it is placed in an awkward sport, in the middle of the class. // There is no one element in this array that can be removed in order to get a strictly increasing, // You can remove 3 from the array to get the strictly increasing sequence [1, 2]. They should be called _ to make clear that they are deliberately ignored: All the elifs can just be ifs, since in all of the conditionals in this method, we either exit the method or the conditional was false. You tell the function when to do something, not ask it if it's ready to do it/if it has it. If you want to minimize space usage, use a generator to join each line of output rather than allocating a list. The description: The border created by "x", as suggested by codefight's user, is to ensure that if mine is at the border of matrix, bomb count won't transfer to the other side. //Any swap of any two elements either in a or in b won't make a and b equal. You could certainly make a case that OP's code doesn't need comments, but that's not true in general. This code works fine until bomb is in the last column of the matrix, for example: The local part, however, also allows a lot of different special characters. | by Leonard Yeo | The Startup | Medium 500 Apologies, but something went wrong on our end.

Where does this (supposedly) Gibson quote come from? Calculating probabilities from d6 dice pool (Degenesis rules for botches and triggers). I'm doing codefight's challange: minesweeper. When needing user input, ensure it's specific, that it's limited, and that you give responses to assist the user to provide the correct input, or allow them to exit the stage where they are.This will enable avoiding runtime errors which crash the program (such as IndexError list assignment index out of range which I encountered) and avoid having try/except/finally statements due to limiting possible inputs.

You can t. For any queries, feel free to comment below. In general, your solution is working (if you uncomment the line #matrix [x].insert (len (matrix)+2, "x") ), but you are making mistakes in your pop () sequence. The function 'show_mines()' is responsible for it. Below we will define an n-interesting polygon. Starting off with some arrangement of mines we want to create a Minesweeper game setup.

Two cells are called neighboring if they share at least one corner.'''. To review, open the file in an editor that reveals hidden Unicode characters. You fixed the bad borders, but OP had a simple if, where you use exception handling as "regular" code logic. Remove the import.
