The 'Chapter24/listing24-6.py' has some error when connecting

[browncrane]

When I connect to the socket,it always complain.
AttributeError, ChatSession instance has no attribute 'room'

I found code with
# Standard setup tasks dispatcher. init (self)
should be :
dispatcher.__init__(self)
and should I use handle_accepted instead of handle_accept ?
I am using py3.6
