Support for scoped IPv6 addresses was implemented in bpo-34788
but missed implementing the .exploded method:
>>> import ipaddress
>>> ipaddress.IPv6Address('fe80::1%eth0').exploded
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
File "/usr/lib/python3.9/ipaddress.py", line 394, in exploded
return self._explode_shorthand_ip_string()
File "/usr/lib/python3.9/ipaddress.py", line 1824, in _explode_shorthand_ip_string
ip_int = self._ip_int_from_string(ip_str)
File "/usr/lib/python3.9/ipaddress.py", line 1705, in _ip_int_from_string
raise AddressValueError("%s in %r" % (exc, ip_str)) from None
ipaddress.AddressValueError: Only hex digits permitted in '1%eth0' in 'fe80::1%eth0'
After this commit:
>>> import ipaddress
>>> ipaddress.IPv6Address('fe80::1%eth0').exploded
'fe80:0000:0000:0000:0000:0000:0000:0001%eth0'

IPv6Interface.exploded silently omitted the scope ID, unlike str() and compressed. Attach it in one place, before the prefix length, so that all three representations agree. Co-Authored-By: Claude Opus 5 (1M context) <[email protected]>

There was a problem hiding this comment.
Fixed support of interfaces. LGTM now.
IPv6Interface.exploded is not documented separately, so reference the classes instead of the attribute. Co-Authored-By: Claude Opus 5 (1M context) <[email protected]>
