Hi all,  
I’d like to extract from a yaml complex dictionary as

node:  
host1:

- { id: ‘1’ }
- { id: ‘2’ }

all values for ‘id’ for ‘host1’

in order to convert this snipped of code from

id\_list: {{ xxx }}

in

id\_list: ‘1’ ‘2’

in python I can do the following

> > > node= {‘test1’:[{‘id’:‘1’},{‘id’:‘2’}]}  
> > > node  
> > > {‘test1’: [{‘id’: ‘1’}, {‘id’: ‘2’}]}  
> > > " “.join([”‘%s’"% x[‘id’] for x in node[‘test1’]]) #this is xxx  
> > > “‘1’ ‘2’”

but in ansible how can obtain the same?

You can use the `map` filter, and the `join` filter.

“{{ node[‘test1’]|map(attribute=‘id’)|join(’ ') }}”

Matt, you saved my day!

With your solution

“‘{{ node[‘test1’] | map(attribute=‘id’) | join(’' '‘) }}’”

I was able to do it,  
thanks a lot!
