What is the class of myobj?

[JXStern]

I want to write something like:

If ClassOf(myobj) == "MyClass": print "OK!"
  or
If ClassOf(myobj) == MyClass: print "OK!"   # no quotes on class

The best I've found in Python is based on str(myobj.__class__).

What's the official way?

Thanks.

Newbie still,
