Python decorator as a staticmethod

by

This is not how staticmethod is supposed to be used. staticmethod objects are descriptors that return the wrapped object, so they only work when accessed as classname.staticmethodname. Example

class A(object):
    @staticmethod
    def f():
        pass
print A.f
print A.__dict__["f"]

prints

<function f at 0x8af45dc>
<staticmethod object at 0x8aa6a94>

Inside the scope of A, you would always get the latter object, which is not callable.

I’d strongly recommend to move the decorator to the module scope — it does not seem to belong inside the class. If you want to keep it inside the class, don’t make it a staticmethod, but rather simply del it at the end of the class body — it’s not meant to be used from outside the class in this case.
