Question

因此，当我尝试运行代码时，我收到了一条错误消息（从previous question继续），我无法弄清楚究竟是什么问题。它说这是一个ValueError，但我无法弄清楚究竟是哪一个。也许现在已经很晚了，但我很茫然。

这是我的代码：

def sort(count_dict, avg_scores_dict, std_dev_dict):
    '''sorts and prints the output'''
    menu = menu_validate("You must choose one of the valid choices of 1, 2, 3, 4 \n        Sort Options\n    1. Sort by Avg Ascending\n    2. Sort by Avg Descending\n    3. Sort by Std Deviation Ascending\n    4. Sort by Std Deviation Descending", 1, 4)
    print ("{0}{1:27}{2:39}{3:51}\n{4}".format("Word", "Occurence", "Avg. Score", "Std. Dev.", "="*51))

    if menu == 1:       
        dic = OrderedDict(sorted(word_avg_dict.items(), key=lambda x:x[1], reverse=False))
        for key in dic:
            print ("{0}{1:27}{2:39:.4f}{3:51:.4f}".format(key, count_dict[key], avg_scores_dict[key], std_dev_dict[key]))
    elif menu == 2:
        dic = OrderedDict(sorted(word_avg_dict.items(), key=lambda x:x[1], reverse=True))
        for key in dic:
            print ("{0}{1:27}{2:39:.4f}{3:51:.4f}".format(key, count_dict[key], avg_scores_dict[key], std_dev_dict[key]))
    elif menu == 3:
        dic = OrderedDict(sorted(std_dev_dict.items(), key=lambda x:x[1], reverse=False))
        for key in dic:
            print ("{0}{1:27}{2:39:.4f}{3:51:.4f}".format(key, count_dict[key], avg_scores_dict[key], std_dev_dict[key]))
    elif menu == 4:
        dic = OrderedDict(sorted(std_dev_dict.items(), key=lambda x:x[1], reverse=True))
        for key in dic:
            print ("{0}{1:27}{2:39:.4f}{3:51:.4f}".format(key, count_dict[key], avg_scores_dict[key], std_dev_dict[key]))

    return None

这是我运行时的输出和错误：

        Sort Options
    1. Sort by Avg Ascending
    2. Sort by Avg Descending
    3. Sort by Std Deviation Ascending
    4. Sort by Std Deviation Descending1

我搞砸了什么？任何和所有的帮助表示赞赏！

您不应在单个规范字段中拥有多个冒号，例如long → 1234l float → 25f short → (short)5 double → (double)25。删除第二个：

{3:51:.4f}

我在哪里搞砸了输出格式？
