From docs.ansible.com:

Ansible is an IT automation tool. It can configure systems, deploy software, and orchestrate more advanced IT tasks such as continuous deployments or zero downtime rolling updates.

Installation

Install the ansible package. The remote machine where you want to automate deployment or configuration tasks only requires a Python interpreter and an OpenSSH server.

Telling Ansible where Python is located

Ansible requires Python on the target machine, Python 3 is supported as a preview [1] but might not work for all modules. By default Ansible assumes it can find a /usr/bin/python on your remote system that is a 2.X or 3.X version of Python, specifically 2.4 or higher.

If some of your modules requires Python 2 you need to tell Ansible where to find Python 2 by setting the ansible_python_interpreter variable in your Ansible inventory file. This can be done succinctly by using host groups in the inventory:

Inventory file
[archlinux]
server1
server2

[debian]
server3

[archlinux:vars]
ansible_python_interpreter=/usr/bin/python2
