[XML-SIG] setAttribute DOM question-newbie

[Patrick K. O'Brien]

Ah, yes. I never use backticks, so I always forget if they do a str() or a
repr(), which is why I never use them. Vicious cycle. And I guess it's never
too soon to start preparing for 2.2 and the type changes. Thanks for the
reminder.

  Always doing str() has different semantics than this or the original
fragment:

>>> class MyObject:
...     def __str__(self):
...         return 'ImaCoolObject'
...
>>> s = MyObject()
>>> str(s)
'ImaCoolObject'
>>> `s`
'<__main__.MyObject instance at 0x8127104>'

  My assertion about code cleanliness was in comparison to using
type(s) != StringType; using isinstance makes more sense when s might
be a subclass of StringType, which will be a possibility in Python
2.2.  In this context, it may not make any difference, but clean
coding gains from consistency.
