Ad-hoc practice
Before you start go to: cd /etc/ansible
edit your host file
then
aguy@Aguys-computer:/etc/ansible$ ansible [your_IP_Here] -m ping -f 10 -u aguy --ask-pass
The above command will ask you the password for "aguy"
This picture is how an ansible playbook works.

I color coded the objects of the code so you can quickly identify where what is what and how ansible playbooks work.
something.yml ~ the index of the playbook ~ the start file in main directory
- name: configure and deploy the webservers and application code
hosts: ServerGroup
sudo: True
remote_user: your_username_here
roles:
- dosomething
ansible.cfg ~ example only - check the color chart to match the code:
# config file for ansible -- http://ansible.com/
# ==============================================
# nearly all parameters can be overridden in ansible-playbook
# or with command line flags. ansible will read ANSIBLE_CONFIG,
# ansible.cfg in the current working directory, .ansible.cfg in
# the home directory or /etc/ansible/ansible.cfg, whichever it
# finds first
[defaults]
# some basic default values...
inventory = /etc/ansible/hosts
#library = /usr/share/my_modules/
#remote_tmp = $HOME/.ansible/tmp
forks = 5
#poll_interval = 15
#sudo_user = root
#ask_sudo_pass = True
#ask_pass = True
#transport = smart
#remote_port = 22
#module_lang = C
# plays will gather facts by default, which contain information about
# the remote system.
#
# smart - gather by default, but don't regather if already gathered
# implicit - gather by default, turn off with gather_facts: False
# explicit - do not gather by default, must say gather_facts: True
#gathering = implicit
