Of course, this brings to mind the fact that there's *already* an
instance stashed inside the random module.
At that point, you might as well just keep the module-level functions,
and rewrite them to be able to pick up on it if you replace _inst
(perhaps suitably renamed as it would be a public variable) with an
instance of a different class.
def __init__(self, name):
self.__name__ = name
def __call__(self, *args, **kwargs):
return getattr(_inst, self.__name__)(*args, **kwargs)
return "<random method wrapper " + repr(self.__name__) + ">"
_inst = Random()
seed = _method('seed')
random = _method('random')
