The new style of class creation, with the declaration of a parent class, created a unified object model in Python, so that the type of an
instantiated class is equal to its class. In Python 2.2-2.7, this is not the case for old-style classes. In Python 3+ all classes are new-style
classes. However, since the behavior can differ from 2.2+ to 3+, explicitly inheriting from object (if there is no better candidate) is
recommended.
Noncompliant code example
class MyClass():
pass
Compliant solution
class MyClass(object):
pass
