Ansible Inventory Definition - INI & YAML

[Trevor]

Well, here I am again, with my bi-monthly query 
pertaining to Ansible Inventory defintions.

Wanting the actual (vertical) syntax for each of the following:

--- canada: children: prod: hosts: srv[1:3]: dev: hosts: srv4

[canada] [canada:children] prod dev [prod] server[1:3] [dev] server4

By the way, which one is INI, and which one is YAML?

yaml:
--- canada: children: prod: hosts: srv[1:3]: dev: hosts: srv4

ini:

[canada] [canada:children] prod dev [prod] server[1:3] [dev] server4

@Trevor Out of curiosity, how do you keep having these without correct vertical formatting?  It sounds from your question like you get them that way, not that you're having problems entering them formatted correctly in the forum software?
