In python, everything is an object. And every object has attributes and methods or functions. Attributes are described by data variables such as name, age, height, etc.
Properties &they are a special kind of attributes that getter, setter, and delete methods have, such as __get__, __set__, and __delete__.
However, Python has a property decorator that provides getter / setter access to an attribute. Properties &it is a special kind of attribute. Basically when Python comes across the following code:
foo = SomeObject () print (foo.bar)
it looks at bar in foo, and then checks bar to see if there is a __get__, __set__, or __delete__ method, and if so, then that is a property. If it's a property, and not just returning a bar object, it will call the __get__ method and return whatever that method returns.
In Python, you can define getter, setter, and delete methods using a property function. If you just need a read property, there is also an @property decorator that you can add above your method.
class C (object): def __init __ (self): self._x = None # C._x is an attribute @property def x (self): "" "I'm the' x' property. "" " return self._x # C._x is a property This is the getter method @ x.setter # This is the setter method def x (self, value): self._x = value @ x.deleter # This is the delete method def x (self): del self._x
