title: How to override constructor of Python class with many arguments?
body: <p>Say, I have a class Foo, extending class Bar. And I want to slightly override Foo's consructor. And I don't want even know what signarure of Bar's constructors is. Is there a way to do this?</p>
  
  <p>If you didn't understand, I mean the following:</p>
  
  <pre><code>class Bar:
     def __init__ (self, arg1=None, arg2=None, ... argN=None):
        ....
  
  
  class Foo (Bar):
      #Here i just want add additional parameter to constructor, but don't want to know anything about Bar's other parameters (arg1, arg2..., argN)
      def __init__ (self, my_new_arg=None, ??? )
         self.new_arg = my_new_arg
         Bar.__init__(self, ??? )
  </code></pre>
  
  <p>Is there a way to put something short and elegant instead of ??? in this code?
  (Maybe some variations of args/kwargs)</p>
