大神帮帮我
1.从键盘上录入学生个数2.依次录入学生学号、语文、数学、英语成绩
3.输入完成后，显示学号成绩及总分
4.设计排序系统：
输入1：按语文降序 输入2：按数学降序 输入3：按英语降序 输入4：按总分降序 输入5：按语文升序 输入6：按数学升序 输入7：按英语升序 输入8：按总分升序
输入其他大于0的数字：提示输入1-8
输入负数：退出查询 dictname = {}
one_result = []
two_result = []
three_result =[]
sum_result=[]
count = []
while True:
print("1.从键盘上录入学生个数")
print("2.依次录入学生学号、语文、数学、英语成绩")
print("3.输入完成后，显示学号成绩及总分")
print("4.设计排序系统")
print("输入负数：退出查询")

break 简陋版，没做异常处理，没做函数封装，没做数据库保存的简陋版本，将就看下呗
