difference between an object property and type property

Some one to help me this, What is the difference between an object pr开发者_Go百科operty and type property? if possible with an example in python.. thanks!

class A:
   class_property = 10

   def __init__(self):
      self.object_property = 20

The difference is that you can access class_property through class A:

print A.class_property

but you can access object_property only through an instance of A:

a = A()
print a.object_property
