New submission from Kenta Tsuna <lay20...@gmail.com>:
ipaddress library tolerate the prefix length with leading zeros.
$ ./python.exe
Python 3.11.0a4+ (heads/main:8fb3649450, Jan 31 2022, 16:39:46) [Clang 13.0.0
(clang-1300.0.29.3)] on darwin
Type "help", "copyright", "credits" or "license" for more information.
>>> import ipaddress
>>> ipaddress.ip_interface('192.0.2.0/0000000024')
IPv4Interface('192.0.2.0/24')
>>> ipaddress.ip_interface('2001:db8::/0000000032')
IPv6Interface('2001:db8::/32')
The explanation of this behavior exists in follow tests.

But, it seems that the explanation does not exists in the document.
