Python 排序从高到低列出并定义变量

这是我的代码，我如何在最后更新name_分数，以便我可以稍后调用它（使用全局）并对其进行排序

with open(class_number, "r") as file: #1
    file.seek(0) #2
    scores = file.readlines() #3
    name_scores = { } #4
    for line in scores: #5
        name, score = line.rstrip('\n').split(':') #6
        score = int(score) #7
        if name not in name_scores: #8
            name_scores[name] = []   #9    # Initialize score list
        name_scores[name].append(score) #10  # Add the most recent score
        if len(name_scores[name]) > 3:   #11
            name_scores[name].pop(0)   #12 

当我尝试在函数外部打印（姓名和分数）时 我得到：

但我不知道我想打印的是不是“姓名分数”

我试着按字母顺序从高到低排列最后三个分数

with open(view_class, "r") as file: #1
    for name in sorted(name_scores): #16
        name_scores = (sort(name_scores, reverse = True))
        print(name, '-', name_scores[name])

是

class\u分数

还是

name\u分数

？打印

print

语句在哪里？@PeterWood name\u分数，我没有在任何地方使用class\u分数为什么？你说：我尝试打印（“class\u分数”）对不起，让我附加一秒钟

with open(view_class, "r") as file: #1
    for name in sorted(name_scores): #16
        name_scores = (sort(name_scores, reverse = True))
        print(name, '-', name_scores[name])
