title: How to make two objects have the same id in python?
body: <p>If I have a class like below:</p>
  
  <pre><code>class Point(object):
      def __init__(self, x, y):
          self.x = x
          self.y = y
  </code></pre>
  
  <p>And have 2 objects:</p>
  
  <pre><code>a = Point(1,2)
  b = Point(1,2)
  </code></pre>
  
  <p>How can I modify class Point to make <code>id(a) == id(b)</code>?</p>
