我的代码收到“无效语法”错误，但我不知道为什么。
我的代码应创建一个二维零列表，然后将零之一更改为一，并检查某些列表值，以查看它是否将返回1或仅返回零。
我定义了一个函数，该函数应返回相邻单元格值的列表，但是由于某种原因，会出现语法错误。这是我的代码:
def test(x,y):
spotX = [(x-1)%height,0,(x+1)%height]
spotY = [(y-1)%height,0,(y+1)%height]
val = []
for a in range(3):
for b in range(3):
if a and b != 2:
val.append(newBoard[spotX[a]][spotY[b]]
return val
语法错误是“return val”行。
