def sort_students(students, order): if order == 0: return sorted(students, key=lambda x: (-x[1], students.index(x))) else: return sorted(students, key=lambda x: (x[1], students.index(x)))
测试样例
students = [("Alice", 85), ("Bob", 90), ("Charlie", 75), ("David", 90)] order = 0 result = sort_students(students, order) for student in result: print(student) ```
