newbee I have an object how to check what's his class?

[consternation]

Thank You for reply but ....
I found solution suggested by You in a tutorial yesterday. For some reason
it doesn't work in my case.

code:
#mem-dictionary in Y class for storing objects
#Y doesn't inherit from X
      for (i,v) in self.mem.items(): 
      print " isinstance(x,X)"
      print  isinstance(v,X)
      print "type(x) is X"
      print type(v) is X
      print v.__class__.__name__
      print v.__class__

result:
isinstance(x,X)
False
type(x) is X
False
<type 'list'>
list

Well I can handle my problem. I will give an extra field in class with it's
name. But I thought that when a language has tools to learn a class of an
object one should use it.
