其中有3個字典的字典

所以我設法將3個txt文件轉換成一個字典列表，但現在我必須將這3個字典放入具有以下結構的超級字典中。其中有3個字典的字典

「123-45-6789」：{「hw」：[98,89,92,75]，「quiz」：[45,36,42,50,29,27,40,41]，「考試「：[175157]}

我提出與所有的都沒有的值的studentids默認字典和我有三個字典稱爲examList，hwList和quizList具有以下結構（值的長度而變化）

{ '709-40-8165'：[168，98]， '560-33-3099'：[176，16]}

所以問題是如何能夠通過默認字典studentid迭代添加以下字典？

下面是一些代碼

fullRoster= dict() 
    idList= [] 
    quizList= [] 
    hwList= [] 
    examList= [] 
    studentids= open("studentids.txt", "r") 
    idList= [line.rstrip()for line in studentids] 
    studentids.close() 
    idList= dict.fromkeys(idList) 
    #hwFile converted into a list and then into a dictionary 
    #the exam and homework files follow the same structure 
    hwFile= open("hwscores.txt", "r") 
    hwList= [line.rstrip().split() for line in hwFile] 
    hwFile.close() 
    #searches for similar ids then places quiz score into single list 
    for i in range (15): 
     for k in range ((len(hwList))): 
      if hwList[i][0]== hwList[k][0] and i!=k: 
       hwList[i].append((hwList[k][1])) 
    hwList= hwList[:15] 
    #adds zero if hw list is not 5 
    for i in range (15): 
     if len(hwList[i])!=5: 
      while len(hwList[i])<5: 
       hwList[i].append(0) 
    #dictionary comprehension to create dictionary 
    hwList= {l[0]: [int(x) for x in l[1:]] for l in hwList}

我想接近它是這樣的：

# Example exam, hw, and quiz score dicts: 
examList = {'709-40-8165': [168, 98], '560-33-3099': [176, 16]} 
hwList = {'709-40-8165': [15, 10], '602-33-3099': [17, 5]} 
quizList = {'709-40-8165': [15, 10]} 

# Add scores for that student ID 
def add_scores(superList, scoreList, scoreType): 
    for studentID,value in scoreList.items(): 
     if studentID not in superList.keys(): 
      superList[studentID] = {} 
     superList[studentID][scoreType] = value 

superList = {} 
add_scores(superList, examList, 'exam') 
add_scores(superList, quizList, 'quiz') 
add_scores(superList, hwList, 'hw') 

print(superList)

這給：

{'602-33-3099': {'hw': [17, 5]}, '709-40-8165': {'exam': [168, 98], 'hw': [15, 10], 'quiz': [15, 10]}, '560-33-3099': {'exam': [176, 16]}}

它遍歷每個dict和增加該學生ID的分數。

以下代碼詳細說明了Brian的答案。

該函數將複製學生記錄，因此它總是返回傳遞給它的記錄的副本（如果有的話），否則它將返回一個新的詞典。

import copy 

def add_scores(scores, description, records=None): 
    """Add scores to student records. 

    Use this function to add scores for multiple different 
    kinds of graded exercises in the following way: 

    >>> exam_scores = {'709-40-8165': [168, 98], '560-33-3099': [176, 16]} 
    >>> hw_scores = {'709-40-8165': [15, 10], '602-33-3099': [17, 5]} 
    >>> quiz_scores = {'709-40-8165': [15, 10]} 
    >>> records = add_scores(exam_scores, 'exam') 
    >>> records = add_scores(quiz_scores, 'quiz', records) 
    >>> records = add_scores(hw_scores, 'hw', records) 
    >>> records == {'560-33-3099': {'exam': [176, 16]}, \ 
        '602-33-3099': {'hw': [17, 5]}, \ 
        '709-40-8165': {'exam': [168, 98], \ 
            'hw': [15, 10], \ 
            'quiz': [15, 10]}} 
    True 

    Parameters 
    ---------- 
    scores : dict 
     each key is a student id 
     each value is a list of scores 
    description : str 
     describes the type of score being added 
    records : dict 
     each key is a student id 
     each value is a dictionary of 
     {description: scores} 

    Returns 
    ------- 
    records : dict 
     student records in the format described above 
    """ 
    records = copy.deepcopy(records) if records else {} 
    for student_id, student_scores in scores.items():
