Consider json or yaml. json comes in the standard library, at least in
version 2.6; yaml does not. I don't know if they are secure, but it's
worth checking.

That depends on what you measure as 'best' - data volume, speed of
transmission, security, data complexity, flexibility, ease of decoding
etc etc.

What's the best format to send data across the wire between processes?
I have some simple 'insensitive' data I need to send from a client, to
a server via a TCP socket. Things like 'count = 10, name="foo"' and so

Hello all. I'm writing a program that needs to capture audio from a soundcard
