如何使用Python和boto3在亚马逊的s3中将多个文件添加到一个文件中？

import boto3

def merge_files(bucket_name, source_files, destination_file):
    # 创建S3客户端
    s3 = boto3.client('s3')

    # 读取源文件内容并拼接
    merged_content = b''
    for file in source_files:
        response = s3.get_object(Bucket=bucket_name, Key=file)
        content = response['Body'].read()
        merged_content += content

    # 将拼接后的内容写入目标文件
    s3.put_object(Body=merged_content, Bucket=bucket_name, Key=destination_file)

# 示例用法
bucket_name = 'your-bucket-name'
source_files = ['file1.txt', 'file2.txt', 'file3.txt']
destination_file = 'merged_file.txt'

merge_files(bucket_name, source_files, destination_file)
