copied!<p>I am not answering what you asked - but below shows what could be a decorator equivalent to <code>classmethod</code>, written in Pure Python - since the one in the source code is in C, inside <a href="http://hg.python.org/cpython/file/8527427914a2/Objects/funcobject.c#l589" rel="nofollow noreferrer"><code>Python-2.7.2/Objects/funcobject.c</code></a> as Mishna puts in his answer.</p> <p>So, the idea of class methods is to use the "descriptor" mechanism, as described in <a href="http://docs.python.org/reference/datamodel.html#implementing-descriptors" rel="nofollow noreferrer">Python's data model</a> - and make it so that the <code>__get__</code> method does return a function object that when called, will call the original method with the first argument pre-filled:</p> <pre><code>class myclassmethod(object): def __init__(self, method): self.method = method def __get__(self, instance, cls): return lambda *args, **kw: self.method(cls, *args, **kw) </code></pre> <p>And on Python console:</p> <pre><code>>>> class MyClass(object): ... @myclassmethod ... def method(cls): ... print cls ... >>> >>> m = MyClass() >>> m.method() <class '__main__.MyClass'> >>> </code></pre> <p><strong>* EDIT - Update *</strong></p> <p>The O.P. further asked "If I wanted the decorator to also accept a parameter what would be the proper format for init? " -</p> <p>In that case it is not only <code>__init__</code> which has to be changed - a decorator that accepts configuration parameters is actually called in "two stages" - the first one annotate the parameters, and returns a callable - the second call accepts only the function which will actually be decorated.</p> <p>There are a few ways to do it - but I think the most straightforward is to have a function that returns the class above, like in:</p> <pre><code>def myclasmethod(par1, par2, ...): class _myclassmethod(object): def __init__(self, method): self.method = method def __get__(self, instance, cls): # make use of par1, par2,... variables here at will return lambda *args, **kw: self.method(cls, *args, **kw) return _myclassmethod </code></pre>
