python名称错误，但我认为名称已定义

好的，我正在学习LPTHW并编写一个游戏。我们应该把游戏分成不同的脚本，看看如何导入它们。我有4个脚本：

ex45.py

执行主代码，

Engine45.py

是引擎，

Locations45.py

是位置列表，

Maps45.py

是保存地图值并在位置间移动的脚本

运行时出现的错误是： 回溯（最近一次呼叫最后一次）： 文件“ex45.py”，第2行，在 导入地图45 文件“C:\Users\raitlin\Python\Maps45.py”，第1行，在 进口地点45 文件“C:\Users\raitlin\Python\Locations45.py”，第4行，在 类映射（对象）： 文件“C:\Users\raitlin\Python\Locations45.py”，第6行，在地图中 “黄金健身房”：黄金健身房（）， NameError:未定义名称“Gold_gym”

我不明白为什么在

Locations45.py

中定义了黄金健身房，但却没有定义它

代码块如下：

ex45.py

import Engine45
import Maps45
import Locations45


a_map = Map('Gold_gym')
a_game = Engine(a_map)
a_game.run()

引擎45.py

class Engine(object):

    def __init__(self, location_map):
        print "Engine __init__ has location_map", location_map
        self.location_map = location_map

    def run(self):
        current_location = self.location_map.opening_location()
        print "Play's first scene", current_location

        while True:
            print "\n"('-' * 20)
            next_location_name = current_location.use()
            print "next location", next_location_name
            current_location = self.location_map.next_location(next_location_name)
            print "map returns new location", current_location

请帮助？

当您：

import Locations45

该模块在名称空间

Locations45

所以当你打电话的时候

Gold_gym()

它在

Maps45

中查找该对象，从不知道在

将行更改为：

如果只导入位置45，它不会导入每个名称，而是将其作为一个组导入。您可以使用句点引用组中的单个内容：

'Gold_gym': Locations45.Gold_gym(),
'Sapphire_gym': Locations45.Sapphire_gym(),
'Cerulean_gym': Locations45.Cerulean_gym(),
'Loser_gym': Locations45.Loser_gym()

或者，您可以专门导入所有名称：

from Locations45 import Gold_gym, Sapphire_gym, Cerulean_gym, Loser_gym

---

这将使这些名称无需使用前缀即可使用。
