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 formatargspec(), 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 Ka-Ping Yee 'Yury Selivanov N) attrgetter) namedtuple OrderedDictZCO_cCs t|tjS)zReturn true if the object is a module.

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.
