how to use property?

[Fernando Jiménez]

Hi guys!

I'm noob in python and I would know how to correctly use the property. I
have read some things about it but I do not quite understand.

I found this:

class C(object):
    def __init__(self):
        self._x = None

    @property
    def x(self):
        """I'm the 'x' property."""
        return self._x

    @x.setter
    def x(self, value):
        self._x = value

    @x.deleter
    def x(self):
        del self._x

But I think it's a bad habit to use _ to change the visibility of the
attributes as in JAVA.
