python自定义字典的扩展类，让字典操作起来更容易，python自定义,类定义如下class e

类定义如下

class easyaccessdict(dict):    def __getattr__(self,name):        if name in self:            return self[name]        n=easyaccessdict()        super().__setitem__(name, n)        return n    def __getitem__(self,name):        if name not in self:            super().__setitem__(name,nicedict())        return super().__getitem__(name)    def __setattr__(self,name,value):        super().__setitem__(name,value)

                                使用范例

>>> d= easyaccessdict()>>> d{}>>> d.foo.bar= 'a'>>> d{'foo':{'bar':'a'}}>>> d['foo']{'bar':'a'}>>> d['foo'].blah= 7>>> d{'foo':{'bar':'a', 'blah':7}}>>> d.a.b.c.e.e.f.g.h= 11
