I wrote the below code

    def decorator(test_func):
        @functools.wraps(test_func)
        def f(*args, **kwargs):
            if (not is_lib_available(lib)):
                raise SkipTest(('%s    is    not    available' % lib.title()))
            return test_func(*args, **kwargs)
        return f
    return decorator
