Is there a shorthand for referring to its own class in a static method?
Say I have this piece of code:
class SuperLongClassName(object): @staticmethod def sayHi(): print 'Hi' @staticmethod def speak(): SuperLongClassName.sayHi() # Is there a shorthand? Yes, use @classmethod instead of @staticmethod. The whole point of @staticmethod is to remove the extra class parameter if you don't need it.
class SuperLongClassName(object): @classmethod def sayHi(cls): print 'Hi' @classmethod def speak(cls): cls.sayHi() You probably want a classmethod. It works like a staticmethod, but takes the class as an implicit first argument.
class Claaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaass(object): @classmethod def foo(cls): print cls.__name__ Claaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaass.foo() # prints Claaa... Warning:
class Subclaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaass( Claaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaass): pass Subclaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaass.foo() # prints Subclaaa... Alternatively, define a shorter alias for your class at module level:
class Claaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaass2(object): @staticmethod def foo(): return _cls2 _cls2 = Claaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaass2 # prints True print (Claaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaass2 is Claaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaass2.foo())
