标题很糟糕，但希望我能在帖子中解释。创建一个小游戏作为我的python宠物项目，目前正在创建清单。在开发游戏时，一切都还不错……直到制作出能够显示所有玩家库存的功能为止。
elif (prompt == "examine"):
print(inventory[1].name)
gameprompt()
好吧，所以我创建了一个列表，该列表基本上包含 Items 中的一堆类。要调用这些类的name元素，我必须执行类似的操作，否则，我只会得到它的存储位置，这对播放器几乎没有用。我尝试过
elif (prompt == "examine"):
print(inventory[].name)
gameprompt()
以为上面的示例将仅打印所有Item对象的名称，但是存在编译错误，因为我没有指定哪个。所以我尝试了〜
elif (prompt == "examine"):
print(inventory[1:1000].name)
gameprompt()
以为它将打印最多1000个的所有Item对象名称，但是我显然没有，所以我认为可以将名称打印到最新的对象并停止，但是又出现了另一个编译错误从这里...
如果仍然要为列表中的所有类对象打印出类的元素，请告诉我。该游戏的完整代码在这里，尽管我认为您不需要它来帮助我解决问题（它也很大）。

答案 0 :(得分：1)
列表理解或map在这里可以完美地工作：
print([item.name for item in inventory])
理解将迭代列表，并用for之前的任何部分将列表中的每个元素“替换”。在这种情况下，它是item.name。
°实际上，它不会替换原始列表中的元素。它将评估为包含已替换项目的新列表。
