Here is just one of the examples available, it's actually googles first
hit for "twisted client example":

The function "finger" shows what is needed to start up a client.

I'd say the ironic thing is that sockets are so often used in a
different way, imposing lots of unnecessary problems (apart from the
fact that this is a rtfm question) :). What twisted gives you for free
is a rock-stable way to do all networking asynchronous, which is no
trivial task to achieve using sockets (i.e. writing a twisted equivalent
from scratch). When you get used to it, it won't be harder to do simple
things, and way easier to do complex things. It's certainly worth the
