我怎样才能得到一份清单, 列出在班级中定义的 批次, 没有输入的类次?

vars(obj) 返回该类中的所有 vars, 不包括不想要的bliltin vars, 如 , , , , , , os , pdb , 等。

最佳回答

您有几种方法可以获取 < code> class 类变量或实例变量。 使用执行内设函数的编码协议,这些协议由双加亮字符包围 (___ 内建_ ) :

class foo:
    baz = 51
    def __init__(self):
        self.bar = 42

>>> vars(foo)
{ __doc__ : None,
  __init__ : <function __init__ at 0x02A35B70>,
  __module__ :  __main__ ,
  baz : 51}
>>> {k:v for k,v in vars(foo).items() if k[:2]!="__" and k[-2:]!="__"}
{ baz : 51}
>>> obj = foo()
>>> vars(obj)
{ bar : 42}

看着医生,我想知道 沃尔斯是不是你想用的

没有争论, vars () 就会像本地人 () 。 注意, 本地人字典只可用于读取, 因为本地人字典的更新被忽略 。

上看到这个问题,这似乎和你所要的差不多。

如果我错了就告诉我
