This module encapsulates the interface provided by the internal special
attributes (co_*, 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
get_annotations() - safely compute an object's annotations

obj may be a callable, class, or module.
Passing in an object of any other type raises TypeError.
Returns a dict. get_annotations() returns a new dict every time
it's called; calling it twice on the same object will return two
different but equivalent dicts.
This function handles several details for you:
* If eval_str is true, values of type str will
be un-stringized using eval(). This is intended
for use with stringized annotations
("from __future__ import annotations").
* If obj doesn't have an annotations dict, returns an
empty dict. (Functions and methods always have an
annotations dict; classes, modules, and other types of
callables may not.)
* Ignores inherited annotations on classes. If a class
doesn't have its own annotations dict, returns an empty dict.
* All accesses to object members and dict values are done
using getattr() and dict.get() for safety.
* Always, always, always returns a freshly-created dict.
eval_str controls whether or not values of type str are replaced
with the result of calling eval() on those values:
* If eval_str is true, eval() is called on values of type str.
* If eval_str is false (the default), values of type str are unchanged.
globals and locals are passed in to eval(); see the documentation
for eval() for more information. If either globals or locals is
None, this function may replace that value with a context-specific
default, contingent on type(obj):
* If obj is a module, globals defaults to obj.__dict__.
* If obj is a class, globals defaults to
sys.modules[obj.__module__].__dict__ and locals
defaults to the obj class namespace.
* If obj is a callable, globals defaults to obj.__globals__,
although if obj is a wrapped function (using
functools.update_wrapper()) it is first unwrapped.

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 or a __delete__ attribute. 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__

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.

'args' is a list of the parameter names.
'varargs' and 'varkw' are the names of the * and ** parameters or None.
'defaults' is an n-tuple of the default values of the last n parameters.
'kwonlyargs' is a list of keyword-only parameter names.
'kwonlydefaults' is a dictionary mapping names from kwonlyargs to defaults.
'annotations' is a dictionary mapping parameter names to annotations.
Notable differences from inspect.signature():
- the "self" parameter is always reported, even for bound methods
- wrapper chains defined by __wrapped__ *not* unwrapped automatically

A good example of such objects are functions compiled with
Cython, which have all attributes that a pure Python function
would have, but have their code statically compiled.

Private helper function. Takes a signature in Argument Clinic's
extended signature format.
Returns a tuple of two things:
* that signature re-rendered in standard Python syntax, and
* the index of the "self" parameter (generally 0), or None if
the function does not have a "self" parameter.

a Represents a parameter in a function signature.
Has the following public attributes:
* name : str
The name of the parameter as a string.
* default : object
The default value for the parameter if specified. If the
parameter has no default value, this attribute is set to
`Parameter.empty`.
* annotation
The annotation for the parameter if specified. If the
parameter has no annotation, this attribute is set to
`Parameter.empty`.
* kind
Describes how argument values are bound to the parameter.
Possible values: `Parameter.POSITIONAL_ONLY`,
`Parameter.POSITIONAL_OR_KEYWORD`, `Parameter.VAR_POSITIONAL`,
`Parameter.KEYWORD_ONLY`, `Parameter.VAR_KEYWORD`.
Every value has a `description` attribute describing meaning.

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.)

If *max_width* integer is passed,
signature will try to fit into the *max_width*.
If signature is longer than *max_width*,
all parameters will be on separate lines.
