title: Inherit specific attributes
body: <p>Is there a way to inherit from a class only specific attributes?</p>
  
  <p>For example,</p>
  
  <pre><code>class basic():
      def __init__(self, a, b, c):
          self.a = a
          self.b = b
          self.c = c
  
  class inher(basic):
      def __init__(self, d, e, f):
          self.d = d
          self.e =e
          self.f = f
  
      def func(self):
          # here use 'a' from basic
  </code></pre>
  
  <p>I know I can inherit everything from basic:</p>
  
  <pre><code>class inher(basic):
      def __init__(self, a, b, c, d, e, f):
          basic.__init__(self, a, b, c) #inherit these from basic
          self.d = d
          self.e = e
          self.f = f
  </code></pre>
  
  <p>Is there a way I can inherit only argument 'a' from basic?</p>
