try this for about any object you can pass to finfo:
----< finfo.py >----------------
import sys, os
if not hasattr(obj, '__name__'):
obj = type(obj)
name = '<%s instance>'%obj.__name__
name = obj.__name__
if type(obj) == type(sys): # module type
modname = name
else: # not module type, but be class now
modname = obj.__module__
mod = sys.modules[modname]
if modname == '__builtin__' or repr(mod) == "<module '%s' (built-in)>"%modname:
path = sys.executable
path = vars(sys.modules[modname]).get('__file__','??')
if path != '??': tmod = os.path.getmtime(path)
else: tmod = '???'
return name, modname, path, tmod
Not very tested, but seems to retrieve info. The file in question for builtins is
the interpreter executable, I supposed.
