Printing out a value from a nested dictionary

I am new to programming.

I'm trying to print out the value of a key within a nested dictionary.

ROOM = ""
ROOM_DESC = ""
ROOM_THIS = ""
ROOM_THAT = ""
ROOM_EXM = ""

randdict = {
  "a1": {
    ROOM: "room name",
    ROOM_DESC: "room desc",
    ROOM_THIS: "room this",
    ROOM_THAT: "room that",
    ROOM_EXM: "room exm",
  }
}

print(randdict["a1"][ROOM] + "\n" + randdict["a1"][ROOM_DESC] + "\n" + randdict["a1"][ROOM_THIS])

The result I was expecting was:

room name
room desc
room this

Instead what I got was:

room exm
room exm
room exm

Not quite sure what went wrong there, an explanation would be appreciated.

The problem here is that all your variables ROOM_* are the same empty string. So your dictionary is being created only with the last key/value ROOM_EXM: "room exm".

You can check that by printing your dictionary.

You should assign some string to your variables ROOM_*. Even something like:

ROOM = "ROOM"
ROOM_DESC = "ROOM_DESC"
ROOM_THIS = "ROOM_THIS"
ROOM_THAT = "ROOM_THAT"
ROOM_EXM = "ROOM_EXM"

Use different values of ROOM, ROOM_DESC, ROOM_THIS, ROOM_THAT and ROOM_EXM. Dictionaries must have unique keys. 

ROOM = "1"
ROOM_DESC = "2"
ROOM_THIS = "3"
ROOM_THAT = "4"
ROOM_EXM = "5"

randdict = {
  "a1": {
    ROOM: "room name",
    ROOM_DESC: "room desc",
    ROOM_THIS: "room this",
    ROOM_THAT: "room that",
    ROOM_EXM: "room exm",
  }
}

print(randdict["a1"][ROOM] + "\n" + randdict["a1"][ROOM_DESC] + "\n" + randdict["a1"][ROOM_THIS])

ROOM, ROOM_DESC, ROOM_THIS, ROOM_THAT and ROOM_EXM are all "". this causes the dictionary to be overwritten, and because the last entry was room exm that is what gets printed (because it wasn't overwritten). If you switch the room variables to be unique it should work

change your keys to the following. 

randdict = {
  "a1": {
    'ROOM' : "room name",
    'ROOM_DESC' : "room desc",
    'ROOM_THIS': "room this",
    'ROOM_THAT': "room that",
    'ROOM_EXM': "room exm",
  }
}


    print(f"{randdict['a1']['ROOM']} \n{randdict['a1']['ROOM_DESC']} \n{randdict['a1']['ROOM_THIS']}")
