If it were me, I'd define three methods, with longer names to

proc.write_nonblocking(data)

Easily doable.
To implement write_nonblocking() on Windows, do you intend to use
SetNamedPipeHandleState() with PIPE_NOWAIT? The documentation
discourages using this:
Note that nonblocking mode is supported for compatibility with
Microsoft LAN Manager version 2.0 and should not be used to
achieve asynchronous input and output (I/O) with named pipes.
And I guess you will need to use a poll/sleep loop to simulate blocking
or multiplexing. If you want expect-like behaviour then you need some
sort of multiplexing.
