crunching ip addresses

[DeaD_EyE]

I often use the fact, that a dict is a set without values, but since Python 3.6 the order is preserved.
So using list(dict.fromkey(iterable)) will keep the order from the original iterable, but will remove duplicates.

from ipaddress import ip_address

spam = [ip_address('192.168.0.1'), ip_address('192.168.0.2'), ip_address('192.168.0.1')]
unique_preserved_order = list(dict.fromkeys(spam))
