我正在和我的朋友一起为编程课制作一个基于文本的游戏，我们避免使用面向对象的东西，所以请避免这些建议。 要使用该程序，我通常会键入"帮助"，然后当我尝试使用这些命令时，我可以向任何方向移动，例如"右"，"左"，"下"和"上"，我收到错误。 这发生在我添加 spawnMonster 命令部分之后

random.choice函数需要一个序列。
在你的代码的先前版本中（或者可能是来自你同学的代码，只是在类似的代码中存在类似但不相同的问题？），您将怪物存储在一个列表中，例如[("Goblin", 1), ("Troll", 3), …]。对于该代码，random.choice有效，因为列表是一个序列。
但是现在你有一个字典。字典不是一个序列。
您只需编写 list(d) 即可获取字典中所有键的列表。因此，您可以这样做：
return random.choice(list(monsters))
但是，从我能说的monsters，你实际上并没有从得到任何好处，那么为什么不首先使用列表呢？
>monsters是一个字典。然而，它被传递给random.choice()，random.choice()接受一个序列作为它的参数（它从中随机选择一个元素）。这不适用于字典，如果您尝试，您将看到KeyError异常。
由于您只想从spawnMonster()返回敌人，因此您可以使用monsters的键，这是一个列表：
monsters = {"Goblin":1, "Troll":3, "Bear":2, "Giant Spider": 1, "Bandit":1, "Goblin Chief":3}
def spawnMonster():
return random.choice(monsters.keys())
更新
由于您使用的是 Python 3，因此您可以改为这样做（也适用于 Python 2）：
def spawnMonster():
return random.choice(tuple(monsters))
