在python中,实现多维数组或矩阵,有两种常用方法: 内置列表方法和numpy 科学计算包方法. 下面以创建10*10矩阵或多维数组为例,并初始化为0,程序如下: # Method 1: list arr1 = [[0]*10 for i in range(10)] arr1[0][0] = 1 print "Method 1:\n", arr1 arr2 = [[0 for i in range(10)] for i in range(10)] arr2[0][0] = 1 pri…
Given a 2D board and a word, find if the word exists in the grid. The word can be constructed from letters of sequentially adjacent cell, where "adjacent" cells are those horizontally or vertically neighboring. The same letter cell may not be us…
