](ch11.html#ifaces_prot_abc) .

[ 1 ](ch01.html#idm139636571282336-marker) [ Story of Jython
](http://hugunin.net/story_of_jython.html) , written as a Foreword to [
_Jython Essentials_ ](http://bit.ly/jython-essentials) (O’Reilly, 2002), by
Samuele Pedroni and Noel Rappin.

[ 2 ](ch01.html#idm139636571249664-marker) See [ “Private and “Protected”
Attributes in Python” ](ch09.html#private_protected_sec) .

[ 3 ](ch01.html#idm139636571247440-marker) I personally first heard “dunder”
from Steve Holden. Wikipedia [ credits ](http://bit.ly/1Vm72Mf) Mark Johnson
and Tim Hochberg for the first written records of “dunder” in responses to the
question “How do you pronounce ` __ ` (double underscore)?” in the python-list
on September 26, 2002: [ Johnson’s message
](https://mail.python.org/pipermail/python-list/2002-September/112991.html) ;
[ Hochberg’s (11 minutes later) ](https://mail.python.org/pipermail/python-
list/2002-September/114716.html) .

[ 4 ](ch01.html#idm139636556225936-marker) In Python 2, you’d have to be
explicit and write ` FrenchDeck(object) ` , but that’s the default in Python
3.
