It actually is written:
>>> import socket
>>> s = socket.socket()
>>> s.connect(('localhost', 1977))
I'm not sure why "Hello," shows up in an xterm but " world" doesn't: it
may be a terminal emulation bug or some legitimate interaction between
all the control sequences included there. But clearly there is a problem
here somewhere - your \n is being translated into \r\r\r\n.
Could you file a ticket in the tracker and attach this tac file?
