学习编码，进行鼻子测试时出现语法错误，我看不到错误

Question

我在以下代码中使用 nosetests 时收到语法错误。

我检查了代码是否与书中的描述相符，没有发现任何错误。这是我正在使用的代码段：

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

这是预期的结果：

     $nosetests
     ...

     Ran 3 tests in 0.008s

     OK

这是我得到的实际结果：

    E

Answer 1

缺少括号。试试这个：

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, [])

Learning to code and a syntax error appears when I conduct nose tests, I can't see the error

python
