为python中方法中使用的每个变量设置对象属性

Question

如何将对象方法中的所有局部变量（几乎）设置为该对象的属性？在

class Obj(object):
    def do_something(self):
        localstr = 'hello world'
        localnum = 1
        #TODO store vars in the object for easier inspection

x = Obj()
x.do_something()
print x.localstr, x.localnum

受Python update object from dictionary的启发，我提出了以下建议：

class Obj(object):
    def do_something(self):
        localstr = 'hello world'
        localnum = 1

        # store vars in the object for easier inspection
        l = locals().copy()
        del l['self']
        for key,value in l.iteritems():
            setattr(self, key, value)

x = Obj()
x.do_something()
print x.localstr, x.localnum
