不确定您想对结果做什么或如何存储它们，但这应该让您开始使用您需要的东西。

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
