title: is there a difference between class(): and class(object): in python 2.6-3.x?
body: <p>Before py2.6 it's been answered here. <a href="https://stackoverflow.com/questions/332255/difference-between-class-foo-and-class-fooobject-in-python">Difference between class foo and class foo(object) in Python</a></p>
  
  <p>But for python2.6+ and python3.x, is the first one wrong?</p>
  
  <p><code>class Foo(): pass</code> vs <code>class Foo(object): pass</code></p>
