This module encapsulates the interface provided by the internal special
attributes (co_*, im_*, tb_*, etc.) in a friendlier fashion.
It also provides some help for examining source code and class layout.
Here are some of the useful functions provided by this module:
ismodule(), isclass(), ismethod(), isfunction(), isgeneratorfunction(),
isgenerator(), istraceback(), isframe(), iscode(), isbuiltin(),
isroutine() - check object types
getmembers() - get members of an object that satisfy a given condition
getfile(), getsourcefile(), getsource() - find an object's source code
getdoc(), getcomments() - get documentation on an object
getmodule() - determine the module that an object came from
getclasstree() - arrange classes so as to represent their hierarchy
getargvalues(), getcallargs() - get info about function arguments
getfullargspec() - same, with support for Python 3 features
formatargvalues() - format an argument spec
getouterframes(), getinnerframes() - get info about frames
currentframe() - get the current stack frame
stack(), trace() - get info about frames on the stack or in a traceback
signature() - get a Signature object for the callable

But not if ismethod() or isclass() or isfunction() are true.
This is new in Python 2.2, and, for example, is true of int.__add__.
An object passing this test has a __get__ attribute but not a __set__
attribute, but beyond that the set of attributes varies. __name__ is
usually sensible, and __doc__ often is.
Methods implemented via descriptors that also pass one of the other
tests return false from the ismethoddescriptor() test, simply because
the other tests promise more -- you can, e.g., count on having the
__func__ attribute (etc) when an object passes ismethod().F�__get__�__set__�r r �

properties (defined in Python) and getsets and members (defined in C).

For each name in dir(cls), the return list contains a 4-tuple
with these elements:
0. The name (a string).
1. The kind of attribute this is, one of these strings:
'class method' created via classmethod()
'static method' created via staticmethod()
'property' created via property()
'method' any other flavor of method or descriptor
'data' not a method
2. The class which defined this attribute (a class).
3. The object as obtained by calling getattr; if this fails, or if the
resulting object does not live anywhere in the class' mro (including
metaclasses) then the object is looked up in the defining class's
dict (found by walking the mro).
If one of the items in dir(cls) is stored in the metaclass it will now
be discovered and not have None be listed as the class in which it was
defined. Any items whose home class cannot be discovered are skipped.

Follows the chain of :attr:`__wrapped__` attributes returning the last
object in the chain.
*stop* is an optional callback accepting an object in the wrapper chain
as its sole argument that allows the unwrapping to be terminated early if
the callback returns a true value. If the callback never returns a true
value, the last object in the chain is returned as usual. For example,
:func:`signature` uses this to stop unwrapping if any object in the
chain has a ``__signature__`` attribute defined.
:exc:`ValueError` is raised if a cycle is encountered.

This function is deprecated, as it does not support annotations or

on the supplied callable.
For a more structured introspection API, use inspect.signature() instead.
Alternatively, use getfullargspec() for an API with a similar namedtuple
based interface, but full support for annotations and keyword-only
parameters.

- the "self" parameter is always reported, even for bound methods
- wrapper chains defined by __wrapped__ *not* unwrapped automatically

It stores a Parameter object for each parameter accepted by the
function, as well as information specific to the function itself.
A Signature object has the following public attributes and methods:
* parameters : OrderedDict
An ordered mapping of parameters' names to the corresponding
Parameter objects (keyword-only arguments are in the same order
as listed in `code.co_varnames`).
* return_annotation : object
The annotation for the return type of the function if specified.
If the function has no annotation for its return type, this
attribute is set to `Signature.empty`.
* bind(*args, **kwargs) -> BoundArguments
Creates a mapping from positional and keyword arguments to
parameters.
* bind_partial(*args, **kwargs) -> BoundArguments
Creates a partial mapping from positional and keyword arguments
to parameters (simulating 'functools.partial' behavior.)
