[BangPypers] Dictionary : An elementary question

[Anand Shankar]

During a tutorial python session with my colleagues I was presented with a basic 
question

>>> d = {'apple':2,'banana':5, 'coke': 6}
>>> print d.keys()
['coke', 'apple', 'banana']


Question is why does it not return

['apple','banana','coke']

Similarly:

>>> d = {'a':2,'b':4,'c':5,'d':4,'e':3}
>>> print d.keys()
['a', 'c', 'b', 'e', 'd']

why not

['a', 'b', 'c', 'd', 'e']

I have no clues. Any inputs??
