你可以在shell中使用dir()列出对象的属性:

>>> dir(object())
['__class__', '__delattr__', '__doc__', '__format__', '__getattribute__', '__hash__', '__init__', '__new__', '__reduce__', '__reduce_ex__', '__repr__', '__setattr__', '__sizeof__', '__str__', '__subclasshook__']

当然，还有inspect模块:http://docs.python.org/library/inspect.html#module-inspect

我很惊讶居然没人提到帮助!

In [1]: def foo():
   ...:     "foo!"
   ...:

In [2]: help(foo)
Help on function foo in module __main__:

foo()
    foo!

Help让您阅读文档字符串并了解类可能具有的属性，这非常有用。

import pprint

pprint.pprint(obj.__dict__)

or

pprint.pprint(vars(obj))

尝试使用:

print(object.stringify())

其中object是要检查的对象的变量名。

这将打印出格式化良好的选项卡输出，显示对象中所有键和值的层次结构。

注意:这在python3中有效。不确定它是否适用于早期版本

更新:这并不适用于所有类型的对象。如果你遇到了这些类型之一(比如Request对象)，请使用以下类型之一:

dir(对象)

or

进口pprint 然后: pprint.pprint (object.__dict__)
