I'm pretty new to python programming and I wanted to try my hand at a simple text adventure game, but I've immediately stumbled on a roadblock.
class userInterface:def __init__(self, roomID, roomDesc, dirDesc, itemDesc):self.roomID = roomIDself.roomDesc = roomDescself.dirDesc = dirDescself.itemDesc = itemDescdef displayRoom(self): #Displays the room descriptionprint(self.roomDesc)def displayDir(self): #Displays available directionsL1 = self.dirDesc.keys()L2 = ""for i in L1:L2 += str(i) + " "print("You can go: " + L2)def displayItems(self): #Displays any items of interestprint("Interesting items: " + str(self.itemDesc))def displayAll(self, num): #Displays all of the abovenum.displayRoom()num.displayDir()num.displayItems()def playerMovement(self): #Allows the player to change rooms based on the cardinal directionsif input( "--> " ) in self.dirDesc.keys():letsago = "ID" + str(self.dirDesc.values())self.displayAll(letsago)else:print("Sorry, you can't go there mate.")ID1 = userInterface(1, "This is a very small and empty room.", {"N": 2}, "There is nothing here.")ID2 = userInterface(2, "This is another room.", {"W": 3}, ["knife", "butter"])ID3 = userInterface(3, "This is the third room. GET OVER HERE", {}, ["rocket launcher"])ID1.displayAll(ID1)ID1.playerMovement()That is my code, which for some reason throws that error:
Traceback (most recent call last):File "D:/Python34/Text Adventure/framework.py", line 42, in <module>ID1.playerMovement()File "D:/Python34/Text Adventure/framework.py", line 30, in playerMovementself.displayAll(fuckthis)File "D:/Python34/Text Adventure/framework.py", line 23, in displayAllnum.displayRoom()AttributeError: 'str' object has no attribute 'displayRoom'I've search on the internet and in python documentation what the hell am I doing wrong here and I have no idea. If I'll put ID2 or ID3 in place of self.displayAll(letsago) it works perfectly, but it's pointless since player has no control over where he wants to go, so I'm guessing there is something wrong with trying to connect ID with the number from the dictionary, but I have no idea what to do and how to fix this.

The problem is in your playerMovement method. You are creating the string name of your room variables (ID1, ID2, ID3):
letsago = "ID" + str(self.dirDesc.values())However, what you create is just a str. It is not the variable. Plus, I do not think it is doing what you think its doing:
>>>str({'a':1}.values())'dict_values([1])'If you REALLY needed to find the variable this way, you could use the eval function:
>>>foo = 'Hello World!'>>>eval('foo')'Hello World!'or the globals function:
class Foo(object):def __init__(self):super(Foo, self).__init__()def test(self, name):print(globals()[name])foo = Foo()bar = 'Hello World!'foo.text('bar')However, instead I would strongly recommend you rethink you class(es). Your userInterface class is essentially a Room. It shouldn't handle player movement. This should be within another class, maybe GameManager or something like that.
