derived class name in python 2.6/2.7

[Sells, Fred]

This is simple, but I just cannot find it after quite a bit of searching

I have this basic design

class A:
def __init__(self):
print 'I am an instance of ', self.__class__.name

class B(A):
pass


X = B
I would like this to print "I am an instance of B" but I keep getting A. Can someone help me out here.

Did you mean to use __name__ instead of name?

I assume that this is
X = B()

If you make those two changes then it should do what you want.

Why would creating an alias for class B execute the initializer for
either class?

perhaps you meant:

x = B()

BTW, since you're on 2.x python, you should derive A from object.
Otherwise it's an old-style class.
