Hi guys,
Continuing my Python learning, I came across an exercise which asks me

way however. ;-)

Now that I had a better look the test is correct. Now it is up to you
to figure out why your index_of() fails. Walter gave you a good hint.

As of version 2.6/3 a tuple does have index(). Not sure which version

Hi all,
Suppose we have
class A(object):
pass
a = A()
Is there any difference between
setattr(a, 'foo', 'bar)
and
a.__setattr__['foo'] = 'bar'
other than syntax?
And which is considered 'better' form in Python?
Cheers,
Rasjid.
