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 get_annotations() - safely compute an object's annotations )zKa-Ping Yee z'Yury Selivanov N) attrgetter) namedtuple OrderedDictCO_iFglobalslocalseval_strc st|trEt|dd}|r!t|dr!|dd}t|tjr d}nd}d}t|dd}|rs z#get_annotations..)rtypegetattrhasattrr typesGetSetDescriptorTypesysmodulesdictvars ModuleTypecallable TypeError ValueErrorr functoolspartialfuncritems) objrrr obj_dictann obj_globals module_namemodule obj_localsunwrap return_valuerrrget_annotationsBsl -                r4cC t|tjS)zReturn true if the object is a module.

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> isfunctionrrr7tprrrismethoddescriptorsrFcCs8t|s t|s t|rdSt|}t|dpt|dS)a}Return true if the object is a data descriptor.
