Добрый день,

У меня есть класс с переменной в которую я хочу писать и из которой я хочу читать используя одну и туже функцию.

class editField(object):
    value = "Read"

    @property
    def text(self):
        return self.value

test = editField()
print test.text
>> Read

test = editField()
print test.text
>> Read
test.text = "Write"
print test.text
>> Write

Простите за банальность, но может так? :)

class Empty:
    pass

test = Empty()
test.text = "TEST"     # присваивание
print test.text        # чтение

2.1 Built-in Functions

…

property( [fget[, fset[, fdel]]])

Return a property attribute for new-style classes (classes that derive from object).
fget is a function for getting an attribute value, likewise fset is a function for setting, and fdel a function for del'ing, an attribute. Typical use is to define a managed attribute x:

class C(object):
    def __init__(self): self._x = None
    def getx(self): return self._x
    def setx(self, value): self._x = value
    def delx(self): del self._x
    x = property(getx, setx, delx, "I'm the 'x' property.")

If given, doc will be the docstring of the property attribute. Otherwise, the property will copy fget's docstring (if it exists). This makes it possible to create read-only properties easily using property() as a decorator:

class Parrot(object):
    def __init__(self):
        self._voltage = 100000

    @property
    def voltage(self):
        """Get the current voltage."""
        return self._voltage

turns the voltage() method into a ``getter'' for a read-only attribute with the same name.

Спасибо, сделал так

>>> class editField(object):
...   def __init__(self):
...     self.value = "Read"
...   @property
...   def text(self):
...     return self.value
...   @text.setter
...   def text(self, val):
...     self.value = val
... 
>>> test = editField()
>>> test.text
'Read'
>>> test.text = "Write"
>>> test.text
'Write'
>>>
