Solve the following python programming problem given the following code:
def decorate_callable(self, func) : 
    if hasattr (patched, 'patchings') : 
        func.patchings.append (self) 
        return func 
@ wraps (func) 
    def patched(* args, **keywargs) : 
        extra_args = [] 
        entered_patchers = [] 
        exc_info = tuple () 
        try : 
            for patching in patched.patchings : 
                arg = patching.__enter__ () 
                entered_patchers.append (patching) 
                if (patching.attribute_name is not None) : 
                    keywargs.update (arg) 
else : 
                    if (patching.new is DEFAULT) : 
                        extra_args.append (arg) 
args += tuple (extra_args) 
            return func (* args, ** keywargs) 
except : 
            if ((patching not in entered_patchers) and _is_started (patching)) : 
                entered_patchers.append (patching) 
exc_info = sys.exc_info () 
            raise 
finally : 
            for patching in reversed (entered_patchers) : 
                patching.__exit__ (* exc_info) 
patched.patchings = [self] 
    return patched
