What you want is an IPv6 class which represents an address in some

to convert the internal form into any of these formats.
Then, instead of attempting to regex your way directly from one string
representation to another, you would do something like:
addr_string = "FEDC:BA98:7654:3210:FEDC:BA98:7654:321"
print IPv6(addr_string).to_short_form()
There are at least 2 third-party IP classes in use. I would not be
surprised if at least one of them does this.
