Properties could be a best practice?

[romeroyonatan]

In the pattern Accessing a protected member from outside the class could be use properties a best practice?

For example

class Rectangle(object):
    def __init__(self, width, height):
        self._width = width
        self._height = height

    @property
    def width(self):
        return self._width

r = Rectangle(5, 6)
# access from property
print("Width: {:d}".format(r.width))

In this way, we ensure read-only access to member and avoid side-effects because the assignment is not allowed
