【问题描述】：

我创建了一个国际象棋观看视频，完成后出现错误

ZeroDivisionError: 除以零

我的整个代码：https://onlinegdb.com/HJR_9t2nD

board = [ ['Rb', 'Nb', 'Bb', 'Qb', 'Kb', 'Bb', 'Nb', 'Rb'], #8
          ['Pb', 'Pb', 'Pb', 'Pb', 'Pb', 'Pb', 'Pb', 'Pb'], #7
          [  0,    0,    0,    0,    0,    0,    0,    0],  #6
          [  0,    0,    0,    0,    0,    0,    0,    0],  #5
          [  0,    0,    0,    0,    0,    0,    0,    0],  #4
          [  0,    0,    0,    0,    0,    0,    0,    0],  #3
          ['Pw', 'Pw', 'Pw',  'Pw', 'Pw', 'Pw', 'Pw', 'Pw'], #2
          ['Rw', 'Nw', 'Bw',  'Qw', 'Kw', 'Bw', 'Nw', 'Rw'] ]#1
          # a      b     c     d     e     f     g     h

def isOccupiedby(board,x,y,color):
    if board[x / y]==0:
        #the square has nothing on it.
        return False

这是完整的错误

【问题讨论】：

是x和y棋盘坐标吗？
@Rabbid 我说的是函数参数不是完整的代码

【解决方案1】：

/ 是除法运算符。如果除数为零，则会出现异常。

您很可能尝试访问网格的某个元素。如果board 是列表列表，则必须连续使用两次订阅运算符。由于网格是按行组织的，所以第一个订阅索引是y，第二个是x：

~~if board[x / y]==0:~~

if board[y][x]==0:
