Dictionary Bug ? Python 1.5 & 2.2

[A.A]

Hello,

I'm not sure if I should call this a bug, but it certainly is very
strange behaviour...

When I input the following at the interpreter:

On Python 1.5:

>>> # A dictionary that has the alphabets a to h as keys, and empty lists 
>>> # as values
>>> a = {'a':[], 'b':[], 'c':[], 'd':[], 'e':[], 'f':[], 'g':[], 'h':[]}
>>> print a
>>> # The result is DISPLAYED in jumpled order
    {'h': [], 'f': [], 'g': [], 'd': [], 'e': [], 'b': [], 'c': [], 'a':
[]}


On Python 2.2:

Here the result is the same as in Python 1.5, but its reversed !
{'a': [], 'c': [], 'b': [], 'e': [], 'd': [], 'g': [], 'h': [], 'h': []}


I came across the above when I tried this code:
  for key in board.keys():
        print key + " \t", board[key]


I've tried it in 'Python 1.5' on Sourceforge's servers, and the result
was the same.


 Best Regards,
