You call 'type' to create a new-style class. The signature is:
"type(name, bases, dict) -> a new type".
>>> def __init__(self):
... print "Creating object of TestClass..."
...
>>> def method1(self):
... print "This is a method"
...
>>> TestClass = type("TestClass", (), {"__init__": __init__, "method1":
>>> method1})
>>>
>>>
>>> help(TestClass)
Help on class TestClass in module __main__:
class TestClass(__builtin__.object)
| Methods defined here:

| __init__(self)

| Data and other attributes defined here:

| __dict__ = <dictproxy object>
| dictionary for instance variables (if defined)

| __weakref__ = <attribute '__weakref__' of 'TestClass' objects>
| list of weak references to the object (if defined)
>>> TestClass()
Creating object of TestClass...
<__main__.TestClass object at 0x00AED0B0>
>>> TestClass().method1()
Creating object of TestClass...
This is a method
