Hmmm, under Python 2.4.X, printing repr(old.__class__) gives me this:
<class exceptions.UnicodeDecodeError at 0x00A24F00>
while under 2.5.X, I get this:
<type 'exceptions.UnicodeDecodeError'>
So, let's try sub-classing the type:
def modify_message(old, f):
class Empty: pass
new = Empty()
print "old.__class__ =", repr(old.__class__)
print "Empty =", repr(Empty)
new.__class__ = Empty
class Excpt(old.__class__): pass
print "Excpt =", repr(Excpt)
print "Excpt.__class__ =", repr(Excpt.__class__)
new.__class__ = Excpt
new.__dict__ = old.__dict__.copy()
new.__str__ = f
return new
Nope, that gives us the same message:
old.__class__ = <type 'exceptions.UnicodeDecodeError'>
Empty = <class __main__.Empty at 0x00AB0AB0>
Excpt = <class '__main__.Excpt'>
Excpt.__class__ = <type 'type'>
Traceback (most recent call last):
[...]
TypeError: __class__ must be set to a class
Excpt ceratinly appears to be a class. Does anyone smarter than me
know what's going on here?
