class - Odd behaviour with simple tree implementation in python -

- 

class node:     children = {}  sequence = [1,2,3,4,5]  tree = node() node = tree item in sequence:     if item not in node.children:         node.children[item] = node()     node = node.children[item]  print tree.children.keys()

i want above code output [1], outputs [1, 2, 3, 4, 5]. why this, , how go fixing it?

node.children class attribute. make instance attribute instead.

class node:   def __init__(self):     self.children = {}

i got following problem: i have object called tempscore game. this object blitted canvas renderer via copypixels method. object not display object. it's score-object (self made). score-object extends object called basicblitarrayobject. basicblitarrayobject extends eventdispatcher (therefore no display object). i tried apply several different tweenlite-plugins tempscore-object (i.e. transformaroundcenter, colormatrixfilter, etc.). nothing happens. absolutely nothing. sometimes error messages (when plugin requires display object , object not display object). far good. according greensock (maker of tweenlite) engine can tween numeric property of object. when plugin transformaroundcenter requires display object tweening have modify plugin working non-display object (tempscore). can't because it's way hard me. my game rests upon code: http://www.8bitrocket.com/book/ch11_blastermines.zip try apply tweenlite object called tempmine inside game class blastermines. ...
