如何在保留标题的同时翻转csv行的顺序？

import csv

def reverse_csv_rows(csv_file):
    # 读取CSV文件
    with open(csv_file, 'r') as file:
        reader = csv.reader(file)
        rows = list(reader)

    # 翻转数据顺序
    rows.reverse()

    # 保留标题
    header = rows[0]
    data = rows[1:]

    # 构建新的CSV数据
    reversed_rows = [header] + data

    # 写入CSV文件
    with open('reversed.csv', 'w', newline='') as file:
        writer = csv.writer(file)
        writer.writerows(reversed_rows)

# 调用函数并传入CSV文件路径
reverse_csv_rows('input.csv')
