问题 I am trying to write a code that determines the winner of a tic-tac-toe game. (This is for a college assignment) I have written the following function to do so: This code only checks for horizontal lines, I haven't added the rest. I feel that this is something that needs a bit of hardcoding. def iswinner(board, decorator): win = True for row in range(len(board)): for col in range(len(board)): if board[row][col] == decorator: win = True else: win = False break Where "board" is a 2D array of

问题 I have a method which is simply storing flag value true for a particular record. My flag attribute has been defined as Boolean which has value true/false in my DynamoDB database. While running this method, somehow instead of storing true value, it is inserting a new column for the flag attribute as number datatype and writing value 1 instead of true. While debugging I can see it is reading the value as "true" but while writing my guess is it is taking 1 for true and 0 for false, and hence

问题 How can I check if 20 variables are all true, or if 20 variables are all false? if possible without using a really long if ... the variables are actually array elements: array('a'=> true, 'b'=> true ...) to make it more clear: if the array has both true and false values return nothing if the array has only true values return true if the array has only false values return false :) 回答1: if(count(array_unique($your_array)) === 1) return current($your_array); else return; 回答2: You could use in

问题 I'm a beginner in python trying to create a RPS game where human is playing against a computer. The game is created such that it would be played over a number of determined rounds (best of 3 rounds). A draw is considered a point for each side. My problem is setting the while condition. Initially I did this: while (player_count + computer_count) != winning_score : where the game ends when all round are played. However there will be instances where not all rounds needs to be played and the

问题 I was wondering if its possible for localStorage to have a Boolean value instead of a string? Using JS only no JSON if its impossible or can be done in JS a different way please let me know thanks http://jsbin.com/qiratuloqa/1/ //How to set localStorage "test" to true? test = localStorage.getItem("test"); localStorage.setItem("test", true); if (test === true) { alert("works"); } else { alert("Broken"); } /* String works fine. test = localStorage.getItem("test"); localStorage.setItem("test",

问题 When I do: from ruamel import yaml seq = ["x", "y", "z", "Y", "true", True] print(yaml.dump(seq, version=(1,1))) it gives: %YAML 1.1 --- [x, y, z, Y, 'true', true] but I expected the y and Y to be quoted, because these get loaded back as booleans because this is YAML 1.1. Moreover this bug, indicates this problem is solved. Why is this bug marked as closed, when it still shows this error even on version ruamel.yaml>=0.15.93? 回答1: You are using the unsafe PyYAML compatibility function dump()

问题 Given a boolean vector, how can I find the longest continuous chunk of TRUE and change the rest TRUE values to FALSE ? For example, given a boolean vector: bool = c(TRUE, TRUE, FALSE, TRUE, TRUE, TRUE, TRUE, FALSE) How can I get a vector like: c(FALSE, FALSE, FALSE, TRUE, TRUE, TRUE, TRUE, FALSE) 回答1: Here's an approach that will highlight all longest chunks of consecutive TRUE s in a boolean vector. That means, if there are, say, two TRUE chunks of the same (max) length, both will be
