That's not quite as easy as you might think. In my testing, calling type(obj.methodName) can give any of the following: <type 'instancemethod'> <type 'function'> <type 'builtin_function_or_method'> There may be others as well. Possibly all you really need is to check if the attribute is callable without caring what type of method or function it is: >>> callable(obj.methodName) True In my opinion, that's the best way. If you are sure that the method won't have side-effects or bugs: >>> try: ... obj.method() ... except: ... print "Not a method" ... (But how can you be sure?) If you insist on an explicit test, try this: import new type(obj.methodName) == new.instancemethod or alternatively: >>> isinstance(obj.methodName, new.instancemethod) True -- Steven -- http://mail.python.org/mailman/listinfo/python-list
