三個主題的標記平均值

Question

我試圖創建一個程序來詢問用戶的用戶名和密碼。如果登錄詳細信息是正確的，程序應詢問學生姓名，然後要求三個分數，每個主題一個分數。該計劃應詢問用戶是否希望輸入其他學生的詳細信息。該計劃應輸出每個主題的平均分數。我無法弄清楚如何爲每個學生輸入每個主題的學生分數，以及如何計算每個主題的平均分數。

你能幫忙嗎？

login="teacher" 
password="school" 

usrnm=input("Please enter your username: ") 
pw=input("Please enter your password: ") 

if (usrnm==login) and (pw==password): 
    print("==Welcome to the Mathematics Score Entry Program==") 
    print("Do you want to enter the students score? Yes/No: ") 
    option = input() 
    option = option.title() 
    student_info = {} 
    student_data = ['Topic 1 : ', 'Topic 2 : ', 'Topic 3 : '] 
    while (option != "No"): 
    student_name = input("Name: ") 
    student_info[student_name] = {} 
    score1 = int(input("Please enter the score for topic 1: ")) 
    student_info[student_name][Topic_1] = score1 
    score2 = int(input("Please enter the score for topic 2: ")) 
    student_info[student_name][Topic_2] = score2 
    score3 = int(input("Please enter the score for topic 3: ")) 
    student_info[student_name][Topic_3] = score3 
    print("Do you want to enter the students score? Yes/No: ") 
    option = input() 
    option = option.title() 
    average = sum(student_info.values())/len(student_info) 
    average = round(average,2) 
    print ("The average score is ", average) 
else: 
    print("Access denied!")

只保留標記從學生的姓名

students = [] 
marks = [] 
option = "" 
while (option != "No"): 
    students.append(input("Name")) 
    marks.append([float(input("Mark_Category1:")), 
        float(input("Mark_Category2:")), 
        float(input("Mark_Category3:"))]) 
    option = input("Add Another?") 

import numpy 
print(numpy.average(marks,0)) 

獨立的，如果你真的想這樣做沒有numpy的

averages = [sum(a)/float(len(a)) for a in zip(*marks)] # transpose our marks and average each column
