如何在python中读取user 2值并找到最高GPA？

如何编写一个python代码，在一行中读取用户的学名和GPA，但如果用户输入一个类似（off）的单词，程序将停止。。我想使用while循环，计算并打印最高的GPA和学生姓名

2个值=第一个int。。二线。 like=GPA。。。名字

data = []
while True:
    inp = [i for i in input("Please enter your name followed by your GPA: ").strip().split()]
    if (len(inp)==1 or inp[0] == 'off'): break
    data.append({'Name':(' '.join([str(i) for i in inp[:-1]])) , 'GPA':float(inp[-1])})

# print(data)

不确定您想对结果做什么，也不确定如何存储结果，但这应该可以让您从需要的内容开始

from collections import defaultdict

def get_mean_grades():
    students = defaultdict(list)
    while True:
        data = input('Enter your GPA followed by your name: ')
        if data.upper() == 'STOP':
            break
        else:
            gpa, name = data.split(' ', 1)
            students[name].append(float(gpa))
    print()
    for student, grades in students.items():
        average = sum(grades) / len(grades)
        print(f"{student} has an average grade of {average}")

Enter your GPA followed by your name: 4.3 Tom Morris
Enter your GPA followed by your name: 2.2 Fred York
Enter your GPA followed by your name: 4.8 Tom Morris
Enter your GPA followed by your name: 3.3 Fred York
Enter your GPA followed by your name: STOP

Tom Morris has an average grade of 4.55
Fred York has an average grade of 2.75

请告诉我们您到目前为止尝试了什么，以及您遇到的错误。谢谢。我不能用split？？是的，为什么不用？：）姓名、成绩（“输入您的姓名和成绩：”）。分级时拆分（“，”）=“停止”：如果等级>=90，等级=80，等级=70，等级=0，等级为0，这就是问题所在。。编写一个程序，从用户那里读取几行输入。每行包括一名学生的姓名和他/她的GPA（实数）。该程序应计算并打印最高GPA（四舍五入至小数点后2位）以及达到该成绩的学生姓名。
