Solve the following python programming problem given the following code:
def __call__(self, f) : 
    def wrapper(f, * args, **kwargs) : 
        if configuration ['type_check'] : 
            self.nargs = f.func_code.co_argcount 
            self.defaults = (f.func_defaults or ()) 
            self.varnames = f.func_code.co_varnames 
            self.file = f.func_code.co_filename 
            self.line = (f.func_code.co_firstlineno + 1) 
            self.check_args (args, kwargs) 
return f (* args, ** kwargs) 
return decorator (wrapper, wrapper)
