我正在为这个项目编写一个函数。我是python的新手，正在网上学习。我正在尝试定义一个函数，该函数可以读取我的玩家所在的房间，并给出与之相关的谜题。到目前为止，这就是我所拥有的，current_room还可以使用另一本字典。我只是在尝试测试运行时不断出现关键错误。如果还有更好的方法，请告诉我。
编辑：使用完整代码更新

基本上，我从上面的代码中观察到的是，你想检查current_room是否等于Lunchroom，或者你的谜语词典中是否有其他房间。因此，您必须检查字典中是否存在关键字，而不是值。此外，以下部分在您的代码中是不正确的if current_room in riddles['name']:
相反，它应该是
if current_room in riddles.keys():
并且代码if riddle == riddles['answer']:的部分不正确，因为您没有将正确的引用传递给字典密钥
应该是if riddle == riddles[current_room]['answer']:
因此，以下是正确的代码和工作演示，供您理解。
riddles = {'Lunchroom': {'name': 'Lunchroom', 'question': 'riddle?', 'answer': 'yes'}}
def room_puzzle(current_room):
global user_inventory
if current_room in riddles.keys():
riddle = input('{}'.format(riddles[current_room]['question'])).strip()
if riddle == riddles[current_room]['answer']: # here you have to define the refrence to the dictionary value, using the parent key first
# user_inventory += 1
print('You gained a key')
else:
print('that is incorrect')
# return user_inventory
else:
print("no such room")
current_room = 'Lunchroom' #let's assume for now
room_puzzle(current_room)
current_room = 'Someroom' #let's now change the current_room and check that
room_puzzle(current_room)
