AttributeError str object has no attribute

Question

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   roomID         self roomDesc   roomDesc         self dirDesc   dirDesc         self itemDesc   itemDesc      def displayRoom self    Displays the room description         print self roomDesc       def displayDir self    Displays available directions         L1   self dirDesc keys           L2              for i in L1                  L2    str i                print  You can go      L2       def displayItems self    Displays any items of interest         print  Interesting items      str self itemDesc        def displayAll self  num    Displays all of the above         num displayRoom           num displayDir           num displayItems        def playerMovement self    Allows the player to change rooms based on the cardinal directions         if input   -- gt      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  lt module gt      ID1 playerMovement     File  D  Python34 Text Adventure framework py   line 30  in playerMovement     self displayAll fuckthis    File  D  Python34 Text Adventure framework py   line 23  in displayAll     num 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    gt  gt  gt str   a  1  values     dict values  1      If you REALLY needed to find the variable this way  you could use the eval function    gt  gt  gt foo    Hello World    gt  gt  gt 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
