Pythonic way set variables if none in __init__

Question

What's the most pythonic or elegant way of achieving this?

def __init__(self, connection=None, some=None, thing=None, else=None):
   if connection is None:
      self.connection = SetConnection()
   else:
      self.connection = connection
.
.

If I have multiple input args like above for which I would like to call another class to instantiate. Any good way to keep it clean looking without being verbose?

You could use a binary operator:

def __init__(self, connection=None, some=None, thing=None, else=None):
    self.connection = connection or SetConnection()

If connection is None (False) it will run SetConnection().
