This is exactly what you asked it to do. :)

try to do something until you get an Exception.  Since that is a
naked except, absolutely any Exception will do.  That you
print out 'Connection error' doesn't mean that you are only
catching exceptions raised by trying to send something to the
other end ... any Exception will do.

So what happens when you press Control-C?

You get a KeyboardInterrupt exception! :)

see: https://docs.python.org/2/library/exceptions.html

And  you are catching it :)
And when you catch it you print  Connection error and keep on
trying.

This is why people were telling you that naked try:except: pairs,
are rarely what you want.  You didn't want to catch control-c but
you caught it anyway.
