如何改进Python中学生分组随机划分的代码

import random

def group_students(students, group_size):
    random.shuffle(students)  # 随机打乱学生列表顺序
    groups = []
    num_groups = len(students) // group_size  # 计算可以分成的组数

    for i in range(num_groups):
        group = students[i * group_size : (i + 1) * group_size]  # 按照组大小划分学生
        groups.append(group)

    # 处理剩余的学生，如果学生数量不是组大小的整数倍
    remaining_students = len(students) % group_size
    if remaining_students > 0:
        last_group = students[-remaining_students:]
        groups.append(last_group)

    return groups

# 示例用法
students = ["Alice", "Bob", "Charlie", "David", "Eve", "Frank", "Grace", "Helen"]
group_size = 3
result = group_students(students, group_size)
for i, group in enumerate(result):
    print(f"Group {i+1}: {group}")
