python学生成绩管理系统

好的，这是一个简单的Python学生成绩管理系统示例：

students = {}

def add_student(name):
    students[name] = {}

def add_score(name, subject, score):
    students[name][subject] = score

def get_average(name):
    scores = students[name].values()
    average = sum(scores) / len(scores)
    return average

def print_report():
    for name, subjects in students.items():
        print(f"{name}:")
        for subject, score in subjects.items():
            print(f"\t{subject}: {score}")
        average = get_average(name)
        print(f"\tAverage Score: {average}")

while True:
    print("1. Add Student")
    print("2. Add Score")
    print("3. Print Report")
    print("4. Quit")
    choice = input("Enter Choice: ")
    if choice == "1":
        name = input("Enter Student Name: ")
        add_student(name)
    elif choice == "2":
        name = input("Enter Student Name: ")
        subject = input("Enter Subject: ")
        score = int(input("Enter Score: "))
        add_score(name, subject, score)
    elif choice == "3":
        print_report()
    elif choice == "4":
        break
    else:
        print("Invalid Choice")

这个系统使用字典来存储学生和他们的成绩。它提供了添加学生、添加成绩、打印报告和退出的选项。你可以根据自己的需要进行修改和扩展。
