我一直在做一个关于tic-tac-toe游戏的程序，它要求两个玩家轮流输入，就像板的坐标，比如(r1,c1)->(r2,c2)->(r3,c3)-> …，其中r是行，c是列，板看起来像
0 1 2
3 4 5
6 7 8
我键入的程序：
board=[0,1,2,3,4,5,6,7,8]
def show():
print(str(board[0])+str(board[1])+str(board[2]))
print(str(board[3])+str(board[4])+str(board[5]))
print(str(board[6])+str(board[7])+str(board[8]))
def check(char,spot1,spot2,spot3):
if board[spot1]==char and board[spot2]==char and board[spot3]==char:
return True
def checkAll(char):
if check(char,0,1,2):
return True
if check(char,3,4,5):
return True
if check(char,6,7,8):
return True
if check(char,0,3,6):
return True
if check(char,1,4,7):
return True
if check(char,2,5,8):
return True
if check(char,0,4,8):
return True
if check(char,2,4,6):
return True
else:
return False
def ChangeSpotInputToAList(spotInput):
spotafter=[]
for i in spotInput:
if i=="(0,0)":
spotafter.append(0)
if i=="(0,1)":
spotafter.append(1)
if i=="(0,2)":
spotafter.append(2)
if i=="(1,0)":
spotafter.append(3)
if i=="(1,1)":
spotafter.append(4)
if i=="(1,2)":
spotafter.append(5)
if i=="(2,0)":
spotafter.append(6)
if i=="(2,1)":
spotafter.append(7)
if i=="(2,2)":
spotafter.append(8)
return spotafter
i=0
spotInput=input().split("->")
spotafter=ChangeSpotInputToAList(spotInput)
for x in spotafter:
show()
if spotafter[x]%2==0:
print("X-->",x)
spot=x
i+=1
char="X"
board[spot]=char
if i==9:
show()
print("Winner: None")
break
if checkAll(char):
show()
print("Winner:",char)
break
if spotafter[x]%2==1:
print("O-->",x)
spot=x
i+=1
char="O"
board[spot]=char
if i==9:
show()
print("Winner: None")
break
if checkAll(char):
show()
print("Winner:",char)
break
我尝试了一些输入，但其中一个始终出错，即
(2,2)->(0,0)->(1,1)->(0,2)->(1,0)->(0,1)，程序显示：012
345

有人知道我错在哪里吗？任何帮助都将不胜感激！
最佳答案
让我们来看一个场景。
spotInput=input().split("->")
spotafter=ChangeSpotInputToAList(spotInput)
如果输入
(2,2)->(2,2)则spotafter = [8,8]现在我进入我的for循环：
for x in spotafter:
show()
if spotafter[x]%2==0:
在我的第一个循环
x = 8和IM试图获得spotafter[8]，它不存在（spotafter只有2个元素）。因为我不知道你的目标，所以我帮不了你更多，但这就是为什么你得到了索引器。
