Using Property In Python
In python, you don't need unnecessary getter and setter. You can get the same thing in a more beautiful way with property. Initially, you can code
class C(object): def __init__(self, x): self.x = x obj = C(5) obj.x = 6 # set print obj.x # get
Later, you can change it to allow getter, setter
class C(object): def __init__(self, x): self._x = x def get_x(self): return self._x def set_x(self, x): self._x = x x = property(get_x, set_x) obj = C(5) obj.x = 6 # set print obj.x # get
You can use class C in almost the same way, but you can add anything else you want to do to get_x, set_x.
