does anyone know how to install python if the target machine has no internet access? Let's say I have python package located on my control machine, is there any way to copy the python package to target machine?
I hope you've found a solution by now, but if not my suggestion would be to use 'local_action' and perform an scp or sftp command.
Lil' update, on ubuntu 18.04 installing python-minimal will prompt interactively for some libssl installation, which then sits there forever. Using test -e /usr/bin/python || (apt -y update && UCF_FORCE_CONFOLD=1 DEBIAN_FRONTEND=noninteractive apt-get -o Dpkg::Options::="--force-confdef" -o Dpkg::Options::="--force-confold" -qq -y install python-minimal) fixes this behavior.

Why is the raw command necessary for this? I've been having trouble running this lately (likely due to @mahlingam's comment above), and I found that this seems to work for me:
- hosts: all
become: true
become_user: root
become_method: sudo
gather_facts: no
pre_tasks:
- name: Install python for Ansible
apt:
update_cache: yes
name:
- python-minimal
- setup: # aka gather_facts
tasks:
...
Just wondering if there's a reason not to do this

Yep, I think it's simply that a target server without python installed, is unable to run normal ansible task steps. Using 'raw' side-steps the need for python.
PS I think bootstrapping a Python 2 installation is now likely to be unnecessary, since Ansible 2.8+ will auto-detect a suitable Python interpreter to use anyway.

If anyone is looking for a solution for Ubuntu 20.04 - change python-minimal to python2-minimal.
FWIW, I've got an ansible role based upon this thread that works for EL/RedHat/Debian/Ubuntu/FreeBSD. I just published it to ansible- galaxy. Would love for some feedback.
