Question

我正在复制我在课堂上为文本冒险任务编写的代码，但它的行为与我在课堂上编写的代码不同。

问题是我的物品没有从我的＆＃34; roomitems＆＃34;他们应该这样。

我只是一个初学者，所以请尽量让我保持简单：）

rooms = ["hallEnt", "hallMid", "snowRoom", "giantNature", "strangeWall", "riverBank"]
roomDirections = {
    "hallEnt":{"e":"hallMid"},

roomDescriptions = {
    "hallEnt":"The hallway continues east, the cave opening is to the north, there is an opening in the south wall, but its too high to reach, there are some snowboots on the ground.",
    "hallMid":"To the east the hallway grows dark, there is a corridor to the south",
    "snowRoom":"The room is a dead end except for a lit lamp on the ground",
    "giantNature":"To the east you see a river, to the south is a wall with some strange lines on it",
    "strangeWall":"It appears to be just a wall, there are some old lines on the wall but you can't make them out.",

    "lilyTwo":"The lilypads all look the same, you can only guess which is the right direction",

根据它如何在房间物品中循环来判断它似乎期望房间物品是一个字符串列表。现在他们只是简单的字符串。也许这些项目应该更像这样：

roomItems = {
    "hallEnt": ["snowboots"],
    "snowRoom": ["lamp"],
    "treasureRoom": ["treasure"],
}

还值得查看列表remove方法，因为它允许您从列表中删除内容而无需手动编写循环。例如：

invItems.remove(playerInput)

当然可以手动编写该循环以了解如何操作，但在此之后，使用内置方法可以使您的大型程序更易于阅读。

编辑：此行还缺少右括号：

for i in range(0, len(roomItems[currentRoom]):

我通过运行脚本找到了这个。您的系统是否未报告错误的行号？
