协助嵌套字典

Question

所以我的代码应该做的是获取学生 ID 并将它们放入字典，然后将他们的家庭作业、考试和测验成绩也放入字典中。

所以它应该看起来像

{'123456':{'exam':[97, 98, 45], 'homework': [44,45]} etc.

所以为了快速起见，我只添加了一部分以专注于作业部分。我将如何将该家庭作业字典添加到学生 ID 的字典中？（家庭作业文件有学号和成绩）

def create_dictionary(idfilename, hwfilename):
    ids = open(idfilename, 'r')
    hw = open(hwfilename, 'r')
    d = {}
    grades = {}
    for i in ids:
        ids.readline()
        i = i.rstrip("\n")
        grades[i] = d
    for h in hw:
        x = hw.readline()
        x.split(' ')
        if h in grades:
            d = [i]
    print(grades)

我关闭了吗？

您的问题不清楚，因为您的输入数据的形式未知。但一般来说，您可以执行以下操作：

out_dict = {'123456':{'exam':[97, 98, 45], 'homework': [44,45]}}

# example of a list with grades. maybe read from a file?
homework_grades = [1,2,3,4]

# appends grades one at a time
for a_grade in homework_grades:
   out_dict['123456']['homework'].append(a_grade)

# or append all grades in one go.
out_dict['123456']['homework'] += homework_grades
