Vars()似乎显示了该对象的属性，但dir()似乎也显示了父类(es)的属性。您通常不需要看到继承的属性，如str, doc。dict等等。

In [1]: class Aaa():
...:     def __init__(self, name, age):
...:         self.name = name
...:         self.age = age
...:
In [2]: class Bbb(Aaa):
...:     def __init__(self, name, age, job):
...:         super().__init__(name, age)
...:         self.job = job
...:
In [3]: a = Aaa('Pullayya',42)

In [4]: b = Bbb('Yellayya',41,'Cop')

In [5]: vars(a)
Out[5]: {'name': 'Pullayya', 'age': 42}

In [6]: vars(b)
Out[6]: {'name': 'Yellayya', 'age': 41, 'job': 'Cop'}

In [7]: dir(a)
Out[7]:
['__class__',
 '__delattr__',
 '__dict__',
 '__dir__',
 '__doc__',
 '__eq__',
 ...
 ...
 '__subclasshook__',
 '__weakref__',
 'age',
 'name']

from pprint import pprint

def print_r(the_object):
    print ("CLASS: ", the_object.__class__.__name__, " (BASE CLASS: ", the_object.__class__.__bases__,")")
    pprint(vars(the_object))

你需要vars()和pprint()的混合:

from pprint import pprint
pprint(vars(your_object))

这个项目修改pprint以显示所有对象字段值，它忽略对象__repr__成员函数，它还递归到嵌套对象。它与python3一起工作，参见https://github.com/MoserMichael/pprintex 你可以通过pip: pip install printex安装它

你实际上是把两种不同的东西混合在一起。

使用dir()， vars()或inspect模块来获取您感兴趣的内容(我使用__builtins__作为示例;你可以用任何物体代替)。

>>> l = dir(__builtins__)
>>> d = __builtins__.__dict__

随你喜欢，把那本词典打印出来吧:

>>> print l
['ArithmeticError', 'AssertionError', 'AttributeError',...

or

>>> from pprint import pprint
>>> pprint(l)
['ArithmeticError',
 'AssertionError',
 'AttributeError',
 'BaseException',
 'DeprecationWarning',
...

>>> pprint(d, indent=2)
{ 'ArithmeticError': <type 'exceptions.ArithmeticError'>,
  'AssertionError': <type 'exceptions.AssertionError'>,
  'AttributeError': <type 'exceptions.AttributeError'>,
...
  '_': [ 'ArithmeticError',
         'AssertionError',
         'AttributeError',
         'BaseException',
         'DeprecationWarning',
...

Pretty print也可以在交互式调试器中作为命令使用:

(Pdb) pp vars()
{'__builtins__': {'ArithmeticError': <type 'exceptions.ArithmeticError'>,
                  'AssertionError': <type 'exceptions.AssertionError'>,
                  'AttributeError': <type 'exceptions.AttributeError'>,
                  'BaseException': <type 'exceptions.BaseException'>,
                  'BufferError': <type 'exceptions.BufferError'>,
                  ...
                  'zip': <built-in function zip>},
 '__file__': 'pass.py',
 '__name__': '__main__'}

尝试ppretty

from ppretty import ppretty


class A(object):
    s = 5

    def __init__(self):
        self._p = 8

    @property
    def foo(self):
        return range(10)


print ppretty(A(), show_protected=True, show_static=True, show_properties=True)

输出:

__main__.A(_p = 8, foo = [0, 1, ..., 8, 9], s = 5)
