Need Help with Encapsulation in Python!

[Soham Mukherjee]

```
    self.a = 1
     self.b = 2
     self.c = 3
     pass

   def __getattribute__(self, name):
     if sys._getframe(1).f_code.co_argcount == 0:
       if name in self.privates:
         raise Exception("Access to private attribute \"%s\" is 
not allowed" % name)
       else:
         return object.__getattribute__(self, name)
     else:
       return object.__getattribute__(self, name)

   def __setattr__(self, name, value):
     if sys._getframe(1).f_code.co_argcount == 0:
       if name in self.privates:
         raise Exception("Setting private attribute \"%s\" is not 
allowed" % name)
       elif name in self.protected:
         raise Exception("Setting protected attribute \"%s\" is 
not allowed" % name)
       else:
         return object.__setattr__(self, name, value)
     else:
       return object.__setattr__(self, name, value)


example = EncapsulationClass()

example.a = 10 # Exception: Setting private attribute "a" is not 
allowed
example.b = 10 # Exception: Setting protected attribute "b" is 
not allowed
example.c = 10 # example.c == 10

example.__dict__["privates"] # Exception: Setting protected 
attribute "b" is not allowed
```

What would actually be wrong with doing something like this?

Is there any better way to achieve encapsulation in Python? 
Please rectify my code if possible.
