TypeError:'builtin_function_or_method'对象是不可取消的

Question

运行此代码时,我从Python解释器中收到一个奇怪的错误:

def make_map():
    map = [[Tile(0, 0) for col in range(MAP_WIDTH)] for row in range(MAP_HEIGHT)]

    for x in range(MAP_WIDTH):
        for y in range(MAP_HEIGHT):     
            map[x][y].tileType = round((libtcod.noise_perlin(noise2d,[y/MAP_WIDTH,x/MAP_HEIGHT])*100), 0)

它在终端返回:

TypeError: 'builtin_function_or_method' object is unsubscriptable 

回溯也指向此功能:

def render_all():
    global color_light_wall
    global color_light_ground

    #go through all tiles, and set their background color
    for y in range(MAP_HEIGHT):
        for x in range(MAP_WIDTH):
            tileType = map[x][y].tileType
            if tileType>30:
                libtcod.console_set_back(con, x, y, color_dark_wall, libtcod.BKGND_SET )
            else:
                libtcod.console_set_back(con, x, y, color_dark_ground, libtcod.BKGND_SET )

    #draw all objects in the list
    for object in objects:
        object.draw()

    #blit the contents of "con" to the root console
    libtcod.console_blit(con, 0, 0, SCREEN_WIDTH, SCREEN_HEIGHT, 0, 0, 0)

我认为他们都与这条线有关: tileType = map[x][y].tileType但是如果有人能够对此有所了解,我会很感激.

谢谢,Elliot Bonneville

编辑:我忘了包含我的Tile类代码和完整的回溯:

class Tile:
    #a tile of the map and its properties
    def __init__(self, tileType, blocked):
        self.tileType = tileType
        self.blocked = blocked

追溯:

  File "kindred.py", line 123, in <module>
    render_all()
  File "kindred.py", line 64, in render_all
    tileType = map[x][y].tileType
TypeError: 'builtin_function_or_method' object is unsubscriptable

Answer 1

这个错误意味着python尝试获取一个变量名称"map",tileType = map[x][y].tileType但是他没有找到任何地方所以它在功能映射中获取构建,这是不可取消的,因为它是一个解释错误消息的内置函数:

TypeError: 'builtin_function_or_method' object is unsubscriptable 

我建议你首先将你的变量名称从"map"更改为不影响任何内置函数的内容,然后当你更改变量名时你应该有一个NameError错误,因为你的变量没有定义所以你应该解决这个问题

希望我做对了,希望这有帮助:)
