The standard library starts with the socket library which lets you do
pretty much anything you want at IP level. (You could go lower still
with the serial io libraries etc but sockets is usually where networking
starts)

On top of that are built lots of support libraries for most of the
common network tasks including ssh, email, web, ftp, xrpc and more

There are third party networking frameworks like twisted that
sit above all that and can create servers as well.

Its not clear where you expect Python to fit into that scenario.
Python could be programmed to do any of it or all of it. (A lot
of work but possible)
