Hi all,
I'm wodering how the information hiding in python is ment. As I understand
there
doesn't exist public / protected / private mechanism, but a '_' and '__'
naming convention.
As I figured out there is only public and private possible as speakin in "C++
manner". Are you all happy with it. What does "the zen of python" say to that
design? (protected is useless?)
class A:
def __init__(self):
self.__z = 1
self._z = 2
self.z = 3
def _getX(self):
return "X"
def __getY(self):
return "Y"
def doAnything(self):
print self.__getY()
class B(A):
def __init__(self):
A.__init__(self)
print dir (self)
>>> b = B()
['_A__getY', '_A__z', '__doc__', '__init__', '__module__', '_getX', '_z',
'doAnything', 'z']
I was a bit surprised about '_A__getY' and '_A__z'.
What would you say to a C++ Programmer about class interfaces in big Python
systems? What is the idea behind the _ and __ naming. Use or don't use '_'
methods ? (As Designer of the software, as Programmer of the software)
Regards Alexander
