How to print only one item from a dictionary with a changeable variable

Question

I am trying to print only one key and value from my dictionary at a time and have it print based on the player current room position. Every solution I tried so far, either prints all of the items, all the items 10 times (the number of how many items there are), or none. I been searching for web for several hours now, any help would be much appreciated!

rooms = {
    'Lower Deck': {'up': 'Main Deck'},
    'Main Deck': {'down': 'Lower Deck', 'forward': 'Main Hallway', 'item': 'Pistol'},
    'Main Hallway': {'right': 'Crew Cabins', 'back': 'Main Deck', 'forward': 'Air Lock'},
    'Crew Cabins': {'back': 'Main Hallway', 'item': 'Dog tags'},
    'Air Lock': {'back': 'Main Hallway', 'forward': 'Crews Lounge'},
    'Crews Lounge': {'back': 'Air Lock', 'right': 'Escape pods', 'left': 'Engineering Room', 'up': 'Operation Room', 'item': 'Grenade'},
    'Escape pods': {'back': 'Crews Lounge'},
    'Engineering Room': {'back': 'Crews Lounge'},
    'Operation Room': {'back': 'Crews Lounge', 'forward': 'Control Center'},
    'Control Center': {'back': 'Operation Room'}
}

This is the best result out of everything I tried so far

for i in rooms:
    i = current_room
    print('The current exit to the room are: {}'.format(rooms[i]))

# output:
The current exit to the room are: {'up': 'Main Deck'}
The current exit to the room are: {'up': 'Main Deck'}
The current exit to the room are: {'up': 'Main Deck'}
...

It will out put a line for the total number of items there are. That is only the first problem, the next problem I have to have it adjust based on what room the player is in. This is what I have currently have for players to move from room to room (this works):

current_room = 'Lower Deck'
command = input("Please enter your move:n").split()
if command[0].capitalize() == 'Go':
    if command[1] in directions:
        room_dict = rooms[current_room]
        if command[1] in room_dict:
            current_room = room_dict[command[1]]
        else:
            print("There is no exit that direction.n")

If you just want to print the exits for the current room, you don’t need to loop over rooms at all.

This will print the exits and where they lead:

print(rooms[current_room])

Or if you just want to print the exits:

for exit in rooms[current_room]:
    print(exit)
