python 3.x - Reading from subdict in python3 -

i have 2 dict. 1 local player data , 1 listing players subdictionaries:

      class gamedata:         def __init__(self):           self.player  =  {'id'           : 1453339642,                            'positionx'    : 123,                            'positiony'    : 0                           }            self.players =  {1453339642:                                   {'name'         : "admin"}                           }      gamedata = gamedata() 

then print out check if works:

            x in gamedata.player:                 print (str(x),':',gamedata.player[x])              print("\n\n")              x in gamedata.players:                 print (str(x))                 y in gamedata.players[x]:                     print ('    ',y,':',gamedata.players[x][y])             print("\n\n") 

this results in:

            id : 1453339642             positiony : 0             positionx : 123              1453339642                  name : admin 

when want access player's id in players instance

            #print(str(type(gamedata.player)))             #print(str(type(gamedata.players)))             print(str(type(gamedata.players[1453339642]))) 

i keyerror result. why?

if put in file, works:

class gamedata:     def __init__(self):         self.player  =  {'id'           : 1453339642,                          'positionx'    : 123,                          'positiony'    : 0         }          self.players =  {1453339642:                          {'name'         : "admin"}         } gamedata = gamedata() print(str(type(gamedata.players[1453339642]))) 

only indentation differs code. there must happening gamedata between instantiation , final print.
