in 1.2 we are told

Note that dictionaries are unordered, meaning that any time you loop through a dictionary, you will go through every key, but you are not guaranteed to get them in any particular order.

what exactly does this mean? When I print out everything in a for loop it always produces the same order? Am I misunderstanding what the above means?

Take a look at this example:

http://pythonfiddle.com/unordered-dict-example

When I iterate over the dictionary, the elements are not printed in the same order I used in the declaration. The order is usually consistent (that is, if I iterate again over the same dict, it should be the same) but you should not rely on this. (However, Python also has an ordered dictionary library.)

P.S. There’s one chance out of 16 that the dictionary will be printed in the correct order, but the concept remains :D
