我正在为一个连续 4 人的简单游戏编写一个类，但我在调用同一个类中的方法时遇到了问题。为了完整起见，这里是整个类(class):
class Grid:
grid = None
# creates a new empty 10 x 10 grid
def reset():
Grid.grid = [[0] * 10 for i in range(10)]
# places an X or O
def place(player,x,y):
Grid.grid[x][y] = player
# returns the element in the grid
def getAt(x,y):
return Grid.grid[x][y]
# checks for wins in a certain direction
def checkLine(player,v,count,x,y):
x = x+v[0]
y = y+v[1]
if x < 0 or x > 9:
return
if y < 0 or y > 9:
return
if Grid.grid[x][y] == p:
count = count+1
if count == 4:
return True
checkLine(player,v,count,x,y)
return False
# returns the number of the player that won
def check():
i = 'i'
for x in range(0,10):
for y in range(0,10):
if Grid.grid[x][y] > 0:
p = Grid.grid[x][y]
f = checkLine(p,0,array(i,[1,0]),x,y)
if f:
return p
f = checkLine(p,0,array(i,[0,1]),x,y)
if f:
return p
f = checkLine(p,0,array(i,[1,1]),x,y)
if f:
return p
f = checkLine(p,0,array(i,[-1,0]),x,y)
if f:
return p
f = checkLine(p,0,array(i,[0,-1]),x,y)
if f:
return p
f = checkLine(p,0,array(i,[-1,-1]),x,y)
if f:
return p
f = checkLine(p,0,array(i,[1,-1]),x,y)
if f:
return p
f = checkLine(p,0,array(i,[-1,1]),x,y)
if f:
return p
return 0
reset = staticmethod(reset)
place = staticmethod(place)
getAt = staticmethod(getAt)
check = staticmethod(check)
checkLine = staticmethod(checkLine)
我试图从 check() 调用 checkLine()，但我收到错误“NameError:全局名称‘checkLine’未定义”。当我改为调用 Grid.checkLine() 时，我得到“TypeError: 'module' object is not callable”
如何调用 checkLine()？

class Grid(object):
grid = None
# creates a new empty 10 x 10 grid
def reset(self):
Grid.grid = [[0] * 10 for i in range(10)]
# places an X or O
def place(self,player,x,y):
Grid.grid[x][y] = player
# returns the element in the grid
def getAt(self,x,y):
return Grid.grid[x][y]
# checks for wins in a certain direction
def checkLine(self,player,v,count,x,y):
x = x+v[0]
y = y+v[1]
if x < 0 or x > 9:
return
if y < 0 or y > 9:
return
if Grid.grid[x][y] == p:
count = count+1
if count == 4:
return True
checkLine(self,player,v,count,x,y)
return False
# returns the number of the player that won
def check(self):
i = 'i'
for x in range(0,10):
for y in range(0,10):
if Grid.grid[x][y] > 0:
p = Grid.grid[x][y]
for vx in range(-1,2):
for vy in range(-1,2):
f = self.checkLine(p,0,array(i,[vx,vy]),x,y)
if f:
return p
return 0
reset = staticmethod(reset)
place = staticmethod(place)
getAt = staticmethod(getAt)
check = staticmethod(check)
checkLine = staticmethod(checkLine)
请您参考如下方法:
摆脱类。为 grid 使用普通函数和模块级变量。 该类(class)对您没有任何帮助。
附言。如果您真的想从类中调用 checkline，您可以调用 Grid.checkline。例如:
class Foo:
@staticmethod
def test():
print('Hi')
@staticmethod
def test2():
Foo.test()
Foo.test2()
打印
Hi
