如何获取目录中最新文件的MD5校验和？

import os
import hashlib

def get_latest_file_md5(directory):
    latest_file = None
    latest_mtime = 0

    for file in os.listdir(directory):
        file_path = os.path.join(directory, file)
        if os.path.isfile(file_path):
            mtime = os.path.getmtime(file_path)
            if mtime > latest_mtime:
                latest_file = file_path
                latest_mtime = mtime

    if latest_file:
        with open(latest_file, 'rb') as f:
            md5 = hashlib.md5()
            while True:
                data = f.read(8192)
                if not data:
                    break
                md5.update(data)
            return latest_file, md5.hexdigest()

    return None

# 示例用法
directory = '/path/to/directory'
result = get_latest_file_md5(directory)
if result:
    file_path, md5_checksum = result
    print(f"最新文件路径：{file_path}")
    print(f"MD5校验和：{md5_checksum}")
else:
    print("目录中没有文件")
