Hello Guys,

i use gazebo 7.0 with Ros kinetic.

First of all i want a ordered List of the models how i add them to the list.

Here is what my code looks like:

class Block:
    def __init__(self, name, relative_entity_name):
        self._name = name
        self._relative_entity_name = relative_entity_name

class Tutorial:

    _blockListDict = {
        'a': Block('cardboard_box', 'link'),
        'b': Block('cabinet', 'link'),
        'c': Block('bookshelf_0', 'link'),
        'e': Block('jersey_barrier', 'link'),
        'd': Block('Dumpster_0', 'link'),
     }

My problem actual is that my order when i print information for the objects is:

cardboard, bookshelf_0 , cabinet, jersey barrier, Dumpster_0

What i am expected was cardboard, cabinet, bookshelf_0 , Dumpster_0, Jersey_barrier.

Any ideas what i am doing wrong?
