Where are Ansible python modules located?
By default, Ansible assumes it can find a /usr/bin/python on your remote system that is either Python2, version 2.6 or higher or Python3, 3.5 or higher.
How do I know if Ansible modules are installed?
Ansible has a very attractive command named ansible-doc. This command will tell all the module details installed in your system.
