In python, is there a way to get the class name in the "static constructor"? I would like to initialize a class variable using an inherited class method.
return 'Hello ' + cls.__name__
staticField = B._getInit()
NameError: name 'B' is not defined
B is not assigned to until the full
class suite has been executed and a class object has been created. For the same reason, the
__name__ attribute on the class is not set until the class object is created either.
You'd have to assign that attribute afterwards:
class A(): @classmethod def _getInit(cls): return 'Hello ' + cls.__name__ class B(A): pass B.staticField = B._getInit()
The alternative is to use a class decorator (which is passed the newly-created class object) or use a metaclass (which creates the class object in the first place and is given the name to use).
