好的，我正在浏览LPTHW并撰写游戏。我们应该将游戏划分为不同的脚本，以查看导入它们的工作原理。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是保存地图值并通过位置。
运行时遇到的错误是： Traceback（最近一次调用最后一次）： 文件“ex45.py”，第2行，in 导入Maps45 文件“C：\ Users \ Raistlin \ Python \ Maps45.py”，第1行，in 导入地点45 文件“C：\ Users \ Raistlin \ Python \ Locations45.py”，第4行，in class Map（对象）： 在Map中输入文件“C：\ Users \ Raistlin \ Python \ Locations45.py”，第6行 'gold_gym'：Gold_gym（）， NameError：名称'Gold_gym'未定义
我不明白为什么我在Locations45.py中定义Gold_gym时没有定义。
以下代码块：

a_game = Engine(a_map)

请帮忙吗？

当你：
import Locations45
该模块是在名称空间Locations45
所以当你打电话
Gold_gym()
它在Maps45中查找该对象，从不知道要查看Locations45。
将行更改为：
locations = {
'Gold_gym' : Locations45.Gold_gym(),
'Sapphire_gym' : Locations45.Sapphire_gym(),
'Cerulean_gym' : Locations45.Cerulean_gym(),
'Loser_gym' : Locations45.Loser_gym()
答案 1 :(得分：1)
如果您只是执行import Locations45，则不会导入每个名称 - 而是将其作为一组导入。您可以使用句点引用组内的各个事物：
'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
可以使这些名称无需使用前缀。
