Property Method Without Class

I have a next code global_variable = 1 @property def method(): # Some magic, for example # incrementing global variable global global_variable global_variable +=

Solution 1:

@properties are meant to be instance properties, defined in a class. E.g.:

classA(object):@propertydefa(self):
      return2

b = A()
b.a
=> 2

If I understand, you're trying to define a module-property (or "global" property). There's no easy/clean way to do that. See this related question.

EDIT: you can also define a classproperty, to make your property more global-like (does not required an instance). classproperty is not a built in, but is easy to define. Here's one way to define it:

classclassproperty(object):def__init__(self, f):
        self.f = classmethod(f)
    def__get__(self, *a):
        returnself.f.__get__(*a)()

Now you can do:

classA(object):@classpropertydefa(self):
      return2

A.a
=> 2

Solution 2:

Observe the following code:

@property
def f():
    return 1

print f

class a(object):
    @property
    def f(self):
        return 2

print a.f
b = a()
print b.f

Output:

<propertyobject at 0x7f892bfb11b0>
<propertyobject at 0x7f892bfb1208>
2

@property only works properly on a class object that has been instantiated.
