title: Global variable Python classes
body: <p>What is the proper way to define a global variable that has class scope in python? </p>
  
  <p>Coming from a C/C++/Java background I assume that this is correct:</p>
  
  <pre><code>class Shape:
      lolwut = None
  
      def __init__(self, default=0):
          self.lolwut = default;
      def a(self):
          print self.lolwut
      def b(self):
          self.a()
  </code></pre>
