 help() 函数

调用内置帮助系统

>>> help(res)
Help on Response in module requests.models object:

class Response(builtins.object)
 |  The :class:`Response <Response>` object, which contains a
 |  servers response to an HTTP request.
 |
 |  Methods defined here:
 |
 |  __bool__(self)
 |      Returns True if :attr:`status_code` is less than 400.
 |
 |      This attribute checks if the status code of the response is between
 |      400 and 600 to see if there was a client error or a server error. If
 |      the status code, is between 200 and 400, this will return True. This
 |      is **not** a check to see if the response code is ``200 OK``.
 |
 |  __enter__(self)
 |
 |  __exit__(self, *args)
 |
 |  __getstate__(self)
 |
 |  __init__(self)
 |      Initialize self.  See help(type(self)) for accurate signature.

vars() 函数

vars([object]) 返回object对象的__dict__属性,其中object对象可以是模块,类,实例,或任何其他有__dict__属性的对象。所以,其与直接访问__dict__属性等价。示例如下(这里是反例,mser对象中没有__dict__属性):

>>> vars(res)

type() 函数

type(object)返回对象object的类型。

>>> type(res)
<class requests.models.Response>

callable() 函数

callable(object):若object对象是可调用的,则返回True,否则返回False。注意,即使返回True也可能调用失败,但返回False调用一定失败。

>>> callable(res)
False
