def gen_rand_data(tensor_arg):
    rand_func = {
                 "randint":__gen_rand_randint
                 }

    func = rand_func[tensor_arg]
    return func(tensor_arg)

def __gen_rand_randint(arg):
    return arg


print(gen_rand_data("randint"))
print(type(gen_rand_data("randint")))

return func(tensor_arg) 实际返回的是"实例化"之后的返回值string类型的"randint"
