Using property in python (See related posts)

In python, you don't need unnecessary getter and setter.
You can get the same thing in a more beautiful way with property.
Initially, you can code
class C(object):
  def __init__(self, x):
    self.x = x

obj = C(5)
obj.x = 6    # set
print obj.x  # get

Later, you can change it to allow getter, setter
class C(object):
  def __init__(self, x):
    self._x = x

  def get_x(self):
    return self._x
  def set_x(self, x):
    self._x = x
  x = property(get_x, set_x)

obj = C(5)
obj.x = 6    # set
print obj.x  # get

You can use class C in almost the same way, but you
can add anything else you want to do to get_x, set_x.
