Python:导入moduel属性错误，LPTHW ex47:

我正在用艰苦的方式学习python的ex47 这是我的代码：

from nose.tools import*
from ex47.game import Room

def test_room():

    gold = Room("GoldRoom",

                """This room has gold in it you can grab. there's a door to the north.""")

    assert_equal(gold.name, "GoldRoom")
    assert_equal(gold.paths, {})

def test_room_paths():

    center = Room("Center", "Test room in the center.")
    north = Room("North", "test room in the north.")
    south = Room("south", "test room in the south.")

    center.add_paths({'north': north, 'south': south})
    assert_equal(center.go('north'), north) 
    assert_equal(center.go('south'), south)


def test_map():

    start = Room("Start", "You can go west and down a hole.")
    west = Room("Trees", "There are trees here, you can go east.")
    down = Room("Dungeon", "It's dark down here, you can go up.")


    start.add_paths({'west': west, 'down': down})
    west.add_paths({'east': start})
    down.add_paths({'up': start})


    assert_equal(start.go('west'), west)
    asset_equal(start.go('west').go('east'), start)
    assert_equal(start.go('down').go('up'), start)

但是，当使用NoTest测试此代码时，我得到的结果是：

Traceback <most recent call last>:
File "c:\Python31\lib\site-packages\nose\case.py", line 197,in runtest
    self.test<*self.arg>
File "C:\path\Ex47\skeleton\tests\ex47_tests.py", line 28, in test_map
    start.add_paths<{'west': west, 'down':down>}
AttributeError: 'Room' object has no attribute 'add_paths'

您声明“add_path在test_room_path（）中运行良好”，但您假设测试是按照您编写它们的顺序运行的。它们通常按字母顺序运行，这意味着测试室路径尚未执行

---

房间代码看起来不正确，您在

def\uuu init\uu

下缩进了

def add\u路径

，这意味着

add\u路径

是在

\uu init\uu

中本地定义的函数，而不是类中的另一个方法。确保你班上所有的

def

关键词都排好了。

谢谢！我真不敢相信我犯了这么愚蠢的错误！对不起！
