I need to get up to speed on iterators. I learned python 1.5~ via
Alan G's book ...
For an example, I've written a subclass of dict where keys are kept in
a ordered fashion is a list called __keys:
#Here is my items function:
def items(self):
""" Return all pairs in order of addition"""
return [(key,self.__dict[key]) for key in self.__keys]
#And here is my iteritems function (currently does exactly the same thing)
def iteritems(self):
""" At this implementation, does exactly the same thing as
method items()"""
for key in self.__keys:
yield (key,self.__dict[key])
I would welcome examples, comments, or pointers to docs that
illustrate how I may use iteritems to extend functionality for
this class.
NOTE: An important thing about this class, is that iteration thru
members must be done in the same manner in which key/value pairs were
added.
I'm currently using Python 2.3.4 on both workstation and internet
servers and must keep backward compatible to that venue.
Thanks
