Why does this not work?

[alain]

I tried the following:

myobj=object()
myobj.newattr=5

results in:


Traceback (most recent call last):
File "<interactive input>", line 1, in ?
AttributeError: 'object' object has no attribute 'newattr'

Any idea?

I think it's because... object has no attribute 'newattr'

what else is there left to say?

try:

myobj=object()
print dir(myobj)

does that contain 'myattr'?

What about this:
class Object(object)ass
myobj=Object()
myobj.newattr=5

and it works !!!
Python allows the dynamic creation of attributes for an instance of an
object.
