[Tutor] Q about .join() Thanks!

[Joaquin Alzola]

>I find out that the outcome for using .join() on a dictionary is totally different than it using on list or string. for example,

 >                 >>> seq4 = {'hello':1,'good':2,'boy':3,'doiido':4}
 >                 >>>
 >                 boy:good:doiido:hello
>So my question is why the outcome doesn't show sequentially as the same sequence of the original seq4?  What pattern do those "keys" of the dictionary in the outcome show ?

Dictionaries are not an ordered sequence.

In order to do that you need to create and OrderedDict (in collections)
