在一段时间后完成对文件的操作的函数

import time

def delayed_file_operation(file_path, operation, delay):
    time.sleep(delay)  # 等待指定的时间

    try:
        if operation == "读取":
            with open(file_path, "r") as file:
                content = file.read()
                return content
        elif operation == "写入":
            with open(file_path, "w") as file:
                file.write("写入文件的内容")
                return "写入成功"
        elif operation == "追加":
            with open(file_path, "a") as file:
                file.write("追加的内容")
                return "追加成功"
        elif operation == "删除":
            os.remove(file_path)
            return "文件删除成功"
        else:
            return "不支持的操作"
    except FileNotFoundError:
        return "文件不存在"
    except Exception as e:
        return str(e)

result = delayed_file_operation("path/to/file.txt", "读取", 5)  # 5秒后读取文件内容
print(result)
