Python noob, Adventure game error

Python Help

Here is the error and my code. It is supposed to be a basic game where a player goes room to room collecting items to defeat a villain, if you can help, thanks! If not, still thanks! (Not sure why the bottom of the code looks like that in the discussion post)

You are in Starting Area.
inventory:
Traceback (most recent call last):

room_dict = rooms[current_room]

You are looking at the way Python manages namespaces. Some code:

>>> def make_room():
...     rooms = {'reception room' : 'Roses room', 'kitchen' : 'Cookers paradise'}
...     return rooms
... 
>>> make_room()
{'reception room': 'Roses room', 'kitchen': 'Cookers paradise'}
>>> rooms
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
NameError: name 'rooms' is not defined

I have defined rooms in make_room, even executed it, why doesn’t it know room? That is because the definition of room in make_room creates a local reference, that does not “escape” from the function.

I already prepared the next step. make_room returns the room dictionary, so when I write:

>>> rooms_in_script = make_room()
>>> rooms_in_script
{'reception room': 'Roses room', 'kitchen': 'Cookers paradise'}
>>> rooms_in_script['kitchen']
'Cookers paradise'

That works. If you want something from a function, return it.

As an aside, try to run your code more often, after you have written little code. Now you have to search all of that code, if you test more often, you know better where to look for the issue.

Thanks so much for the reply, I will adjust my code and give it a shot.
