 suppose there is a map:
   zoneB_db_static_name_list: {
       "node0": "dltasVM003jeguan",
       "node1": "dltasVM004jeguan"
       ........
       ........
   }
The number of Key:Value pairs in the map are not a constant, sometimes it is 3 or 4, sometimes it is other number.
Is there any way that I can get all the value in this map?

Thank you very much.

This question is about the heat template. Not Python.

It very simple to do this by dict.values() method.
e.g.

zoneB_db_static_name_list={"node0": "dltasVM003jeguan", "node1": "dltasVM004jeguan"}
values = zoneB_db_static_name_list.values()
print values

The result will be:

['dltasVM004jeguan', 'dltasVM003jeguan']

Thank you very much for your kind answer. I am sorry for my not showing my question clearly. This question is about the heat template, that is, I want to know how to get all value in a list when it is in heat template. I am not asking "how to get the value in a list for python".
