Following an example from a book, I'm getting an unexpected outcome.
The point of exercise is to extend operator overloading methods from
a superclass and track the method calls. Here's the code,
class MyList:
def __init__(self, start):
self.wrapped = [ ]
for x in start: self.w

Tthe simplest, IMHO, is :

foo['d'] = foo
is a tad more interestin
Dear Hoffmann, I am also a Newbie and I am currently going through "A Byte
of Python" tutorial from Swaroop C H.
http://www.byteofpython.info/download?PHPSESSID=c0d52343d90f69f25942f49df9ae7944
If you are completely new to programming like me, you will find that this
tutorial is excellent.
Good
