Question

教師が学生ID番号と生徒の成績を入力できるクラスの課題を終了します。最終学年は計算され、学生番号の隣に返されます。私は最終的なグレードを計算することはできますが、グレードを学生のリストに追加することはできません。

def assignments(): 
    assign1 = int(input("Assignment 1 grade: ")) 
    if assign1 > 100: 
     print ("Please input a valid grade value.") 
     assign1 = int(input("Assignment 1 grade: ")) 
    assign2 = int(input("Assignment 2 grade: ")) 
    if assign2 > 100: 
     print ("Please input a valid grade value.") 
     assign2 = int(input("Assignment 2 grade: ")) 
    assign3 = int(input("Assignment 3 grade: ")) 
    if assign3 > 100: 
     print ("Please input a valid grade value.") 
     assign3 = int(input("Assignment 3 grade: ")) 
    assign4 = int(input("Assignment 4 grade: ")) 
    if assign4 > 100: 
     print ("Please input a valid grade value.") 
     assign4 = int(input("Assignment 4 grade: ")) 
    assign5 = int(input("Assignment 5 grade: ")) 
    if assign5 > 100: 
     print ("Please input a valid grade value.") 
     assign5 = int(input("Assignment 5 grade: ")) 
    assign6 = int(input("Assignment 6 grade: ")) 
    if assign6 > 100: 
     print ("Please input a valid grade value.") 
     assign6 = int(input("Assignment 6 grade: ")) 
    assign7 = int(input("Assignment 7 grade: ")) 
    if assign7 > 100: 
     print ("Please input a valid grade value.") 
     assign7 = int(input("Assignment 7 grade: ")) 
    assign8 = int(input("Assignment 8 grade: ")) 
    if assign8 > 100: 
     print ("Please input a valid grade value.") 
     assign8 = int(input("Assignment 8 grade: ")) 
    assign9 = int(input("Assignment 9 grade: ")) 
    if assign9 > 100: 
     print ("Please input a valid grade value.") 
     assign9 = int(input("Assignment 9 grade: ")) 
    assign10 = int(input("Assignment 10 grade: ")) 
    if assign10 > 100: 
     print ("Please input a valid grade value.") 
     assign10 = int(input("Assignment 10 grade: ")) 
    assignGrade = assign1 + assign2 + assign3 + assign4 + assign5 + assign6 + assign7 + assign8 + assign9 + assign10 
    aGrade = assignGrade/10 
    print("The final grade for all assignments is: ") 
    print(aGrade) 
    midterm = int(input("Midterm grade: ")) 
    if midterm > 100: 
     print ("Please input a valid grade value.") 
     midterm = int(input("Midterm grade: ")) 
    finalExam = int(input("Final Exam grade: ")) 
    if finalExam > 100: 
     print ("Please input a valid grade value.") 
     finalExam = int(input("Final Exam grade: ")) 
    testsGrade = midterm + finalExam 
    tGrade = testsGrade/2 
    print("The final grade for all test is: ") 
    print(tGrade) 
    participation = int(input("Participation grade: ")) 
    if participation > 100: 
     print ("Please input a valid grade value.") 
     participation = int(input("Participation grade: ")) 
    partGrade = participation 
    print("The final grade for Participation is: ") 
    print(partGrade) 
    finalGrade = aGrade + tGrade + partGrade/3 


def students(): 
    netIDList = [] 
    maxLengthList = 6 
    while len(netIDList) < maxLengthList: 
     ID = input("Enter Student's Net ID: ") 
     netIDList.append(ID) 
    for s in netIDList: 
     print("Please input grades for student " + s) 
     assignments() 
     f = assignments().finalGrade 
     netIDList.append(": " + f) 
    print(netIDList) 

def main(): 
    students() 

main() 

Answer 1

あなたの問題はここにある：それはオブジェクトではなく機能であるよう

f = assignments().finalGrade 
netIDList.append(": " + f) 

あなたがassignmentsにアクセスしています。 assignmentsに追加する値を戻したいとします。

def assignments(): 
    # do all your input and calculation here 
    finalGrade = aGrade + tGrade + partGrade/3 
    return finalGrade 

このように、関数はこの値を呼び出し元の場所に戻します。その後、変更

f = assignments().finalGrade 

EDIT

f = assignments() 

へ：あなたのように、基本的になりますforループ：

for s in netIDList: 
     print("Please input grades for student " + s) 
     f = assignments() 
     netIDList.append(": " + f) 

が、これはやや紛らわしいリストになります。

[student1_name, student2_name, student1_score, student2_score] 

だから私は辞書を使用します： `` を返す使用

for s in netIDList: 
    print(s + ' final score:' + student_score_map[s])
