## inv.py
"""
Display Ansible inventories as a tree of environments, groups and hosts as leaves.

A nice diversion/excuse to dive into the rich console library.
It will expand simple host ranges, allowing grep commands to find
group names for given hosts.

Usage:
  ./inv.py
  ./inv.py | grep -B10 some-hostname

"""
Update an existing Cloudpassage FirewallZone from an external list of IPs
Wanted to use this to block abusive IPs, then I made this work and
realized it only accepts max 6000 characters, which in practice translates
to ~400 IP addresses, so it's probably not worth using in any case.
