批量亚马逊网络服务S3文件是否存在验证？

pip install boto3

import boto3

# 替换为您的AWS访问密钥和秘密密钥
aws_access_key_id = "YOUR_ACCESS_KEY"
aws_secret_access_key = "YOUR_SECRET_KEY"

# 替换为您的S3存储桶名称
bucket_name = "your-bucket-name"

# 用您想检查的文件列表替换这个列表
files_to_check = [
    "file1.jpg",
    "file2.jpg",
    "file3.jpg",
]

# 创建S3客户端
s3_client = boto3.client(
    "s3",
    aws_access_key_id=aws_access_key_id,
    aws_secret_access_key=aws_secret_access_key,

# 检查文件是否存在的函数
def check_file_exists(bucket, file):
    try:
        s3_client.head_object(Bucket=bucket, Key=file)
        return True
    except Exception as e:
        print(f"File '{file}' does not exist.")
        return False

# 检查每个文件并输出结果
for file in files_to_check:
