python - Why dictionary values aren't in the inserted order?

Question

When i declare a list 1,2,3,4 and i do something with it , even just print i get back the same sequence 1,2,3,4.

But when i do anything with dictionaries , they always change number sequence , like it is being sorted in a twisted way i can't understand .

test1 = [4,1,2,3,6,5]
print test1
test2 = {"c":3,"a":1,"b":2,"d":4}
print test2 

[4, 1, 2, 3, 6, 5]
{'a': 1, 'c': 3, 'b': 2, 'd': 4}

How in the world did 'a' become the first element and 'c' , even if it alphabetically sorted the dictionary it should have been 1,2,3,4 or a,b,c,d not 1,3,2,4 . wT?F @!$!@$#@!

So how do i print , get values from dictionary without changing the positions of the elements .?

Dictionaries in Python are unordered by definition. Use OrderedDict if you need the order in which values were inserted (it's available in Python 2.7 and 3.x).
