Got it.
1, 2, 3 < = simiple list, in python/yaml/json (stuff ansible uses) it
is normally in brackets mylist= [1,2,3], lists can be referenced by a
number that describes the position (normally starting by 0) mylist[1]
would return 2
Ok.
a dict, hash or associative array is a special list that uses names,
normally represented with {}
mydict = { 'one': 1, 'two': 2, 'three', 3}, to access an item you use
the names: mydict['two'] returns 2.
Ok.
in yaml starting with a '-' normally indicates a list item
mylist:
- 1
- 2
- 3
Ok.
for dicts just ignore the - and add the name
mydict:
one: 1
two: 2
three: 3
Ok.
That wasn't too bad :) Small addition. In my first few hours with
Ansible I needed this one for file copying from src to dst:
mydict:
- src: file1.txt
dst: /some/where/file_1.txt
Thank you for your explanation. That was most helpful. For the archives,
the Ansible examples on github also provide a ton of enlightening info
on how to do things:

Cheers,
