Sorry, my mistake.
I realise now that you're creating a whole new function, dedicated to
the special (but extremely common) case of creating a fully connected
client socket. My fault for not realising that first off.
So, a question I would ask is: Is "connect" the right name for that function?
- Will users get confused between the "connect" function and
socket.connect method? They are doing different things.
- Will the naming give rise to the question "the socket-module-level
function connect() takes a timeout parameter, why doesn't the
socket-method connect() take a timeout parameter as well?"
Perhaps a better name might be "create_connected_client_socket", or
something equally descriptive?
Another question I would ask is: "How do I ensure that my newly
created connected client socket is in blocking mode, *without* making
any assumptions about the value of socket.getdefaulttimeout()?"
If the answer to this question is "you can't", then I would suggest a
function signature and implementation like this instead
def connect(address, **kwargs):
This would of course mean that the user would have to explicitly name
the 'timeout' parameter, but that's a good thing in this case, IMO.
