Simply because it didn't occur to me. So now I have
>>> class A: pass
...
>>> d = {A:[A(),A(),A()]}
>>> a = d[A].pop()
>>> a
<__main__.A instance at 0x00F09A58>
>>>
Thanks all!

Why don't you use the class objects themselves as dict keys?

Well, it's true that you can override the __hash__ method to do whatever
you want, but I believe the default for class __hash__ methods is to
return the class id, which should

That does seem unwise (as Teal'c would have uttered). The spec says:
hash( object)
Return the hash value of the object (if it has one). Hash values are

Thanks!
Not so strange I think, the hash values of classes will be used as keys
in a dictionary that serve as an object pool.
Sorry about the double posting, I got a 'server error' message the
first time, so I figured it hadn't gone trhough.

You only had to post the question once. It seems a strange thing to want,
but just do:
hash(a.__class__)

Hello,
Is there any way that I can find the hash value of a class from an
instance?
>>> class A:
... pass
...
>>> a = A()
>>> hash(A)
10782976
>>> hash(a)
12251904
>>>
What I want is a function that returns the value of 'hash(A)':
> a.getHashOfClass()
10782976
Is this possible?
