This module encapsulates the interface provided by the internal special attributes (func_*, 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 getargspec(), getargvalues(), getcallargs() - get info about function arguments 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 s Ka-Ping Yee <ping@lfw.org>s 1 Jan 2001i����N( t attrgetter( t namedtuplei i i i i i i@ i c C s t | t j � S( s� Return true if the object is a module.

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__.

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 im_func attribute (etc) when an object passes ismethod().t __get__t __set__( t hasattrR t isfunctionR ( R ( ( s /usr/lib/python2.7/inspect.pyt ismethoddescriptorN s c C s t | d � o t | d � S( s� Return true if the object is a data descriptor.
