>>> class First(object):
...     def __init__(self):
...         print 'init 1-before'
...         super(First, self).__init__()
...         print 'init 1-after'
...
>>> class Second(object):
...     def __init__(self):
...         print 'init 2-before'
...         super(Second, self).__init__()
...         print 'init 2-after'
...
>>> class Join(First, Second):
...     def __init__(self):
...         print 'init 3-before'
...         super(Join, self).__init__()
...         print 'init 3-after'
...
>>> Join()
init 3-before
init 1-before
init 2-before
init 2-after
init 1-after
init 3-after
<__main__.Join object at 0xb7b5fb6c>
