ZeroDivisionError：在 chess.py 中被零除

问题描述

我创建了一个国际象棋视频，当它完成时出现错误

ZeroDivisionError: 除以零

board = [ ['Rb','Nb','Bb','Qb','Kb','Rb'],#8
          ['Pb','Pb','Pb'],#7
          [  0,0],#6
          [  0,#5
          [  0,#4
          [  0,#3
          ['Pw','Pw','Pw'],#2
          ['Rw','Nw','Bw','Qw','Kw','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

这里是完整的错误

解决方法

/ 是除法运算符。如果除数为零，则会出现异常。

您很可能试图访问网格的元素。如果 board 是列表列表，则必须连续使用订阅运算符两次。由于网格是按行组织的，第一个订阅索引是 y，第二个是 x：

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

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