both mean the same thing and are used to reference local socket files

if you do a `man socket`

one of the lines says

PF_LOCAL        Host-internal protocols, formerly called PF_UNIX,

(AF and PF mean the same thing here, but importantly it shows that PF_UNIX has been depreciated)

this change gives users the option to type socket.AF_LOCAL as well as socket.AF_UNIX when specifying the address family for the socket.

this is my first issue so lmk if there is anything I'm missing )

The socket type is known as AF_UNIX, AF_LOCAL, Unix domain socket, and IPC (inter process communication) socket. The man page unix(7) http://man7.org/linux/man-pages/man7/unix.7.html uses three of those four terms to explain the socket type:

    The AF_UNIX (also known as AF_LOCAL) socket family is used to
    communicate between processes on the same machine efficiently.
    Traditionally, UNIX domain sockets can be [...]

The strace command also uses the name AF_UNIX and not AF_LOCAL. HTTP over AF_UNIX often uses http+unix:// or unix:// to refer to a socket file.

I'm -1 to add the alias. It just adds to the confusion. It's also against the Zen of Python: "There should be one-- and preferably only one --obvious way to do it."

Agreed with the zen of python.
