扩张这串Python代码选择界面：def count_virus_filespath virus_count = 0 if ospathexistspath if ospathisdirpath files = oslistdirpath for file in files file_path =

4. 添加一个函数 quarantine_virus_files，用于将病毒文件移动到隔离目录中：

def quarantine_virus_files(path):
    quarantine_path = os.path.join(os.getcwd(), "Quarantine")
    if not os.path.exists(quarantine_path):
        os.mkdir(quarantine_path)
    if os.path.exists(path):
        if os.path.isdir(path):
            files = os.listdir(path)
            for file in files:
                file_path = os.path.join(path, file)
                if os.path.isfile(file_path):
                    if is_virus(file_path):
                        new_path = os.path.join(quarantine_path, file)
                        os.rename(file_path, new_path)
                        print('已经隔离文件：', new_path)
                elif os.path.isdir(file_path):
                    quarantine_virus_files(file_path)

5. 添加一个函数 clean_quarantine_directory，用于清空隔离目录：

def clean_quarantine_directory():
    quarantine_path = os.path.join(os.getcwd(), "Quarantine")
    if os.path.exists(quarantine_path) and os.path.isdir(quarantine_path):
        files = os.listdir(quarantine_path)
        for file in files:
            file_path = os.path.join(quarantine_path, file)
            if os.path.isfile(file_path):
                os.remove(file_path)
                print('已经删除文件：', file_path)
        os.rmdir(quarantine_path)

6. 完整的代码如下：

import os

def is_virus(file_path):
    # 判断文件是否是病毒文件的逻辑
    pass

def scan_directory(path):
    # 扫描目录的逻辑
    pass

def count_virus_files(path):
    virus_count = 0
    if os.path.exists(path):
        if os.path.isdir(path):
            files = os.listdir(path)
            for file in files:
                file_path = os.path.join(path, file)
                if os.path.isfile(file_path):
                    if is_virus(file_path):
                        virus_count += 1
                elif os.path.isdir(file_path):
                    virus_count += count_virus_files(file_path)
    return virus_count

def quarantine_virus_files(path):
    quarantine_path = os.path.join(os.getcwd(), "Quarantine")
    if not os.path.exists(quarantine_path):
        os.mkdir(quarantine_path)
    if os.path.exists(path):
        if os.path.isdir(path):
            files = os.listdir(path)
            for file in files:
                file_path = os.path.join(path, file)
                if os.path.isfile(file_path):
                    if is_virus(file_path):
                        new_path = os.path.join(quarantine_path, file)
                        os.rename(file_path, new_path)
                        print('已经隔离文件：', new_path)
                elif os.path.isdir(file_path):
                    quarantine_virus_files(file_path)

def clean_quarantine_directory():
    quarantine_path = os.path.join(os.getcwd(), "Quarantine")
    if os.path.exists(quarantine_path) and os.path.isdir(quarantine_path):
        files = os.listdir(quarantine_path)
        for file in files:
            file_path = os.path.join(quarantine_path, file)
            if os.path.isfile(file_path):
                os.remove(file_path)
                print('已经删除文件：', file_path)
        os.rmdir(quarantine_path)

def restore_quarantine_files():
    quarantine_path = os.path.join(os.getcwd(), "Quarantine")
    if os.path.exists(quarantine_path) and os.path.isdir(quarantine_path):
        files = os.listdir(quarantine_path)
        for file in files:
            file_path = os.path.join(quarantine_path, file)
            if os.path.isfile(file_path):
                new_path = os.path.join(os.getcwd(), os.path.basename(file_path))
                os.rename(file_path, new_path)
                print('已经恢复文件：', new_path)
        os.rmdir(quarantine_path)

path = input("请输入要操作的目录路径：")
action = input("请选择要执行的操作：\n1. 扫描目录并统计病毒文件数量\n2. 隔离病毒文件\n3. 清理隔离目录并恢复文件到原始目录\n")

if action == '1':
    scan_directory(path)
    virus_count = count_virus_files(path)
    print('共发现', virus_count, '个病毒文件')
elif action == '2':
    quarantine_virus_files(path)
    print('已经隔离所有病毒文件')
elif action == '3':
    clean_quarantine_directory()
    print('已经清理隔离目录')
    restore_quarantine_files()
    print('已经恢复隔离文件到原始目录')
else:
    print('无效的操作')

这个扩展的代码选择界面可以执行以下操作：

• 扫描目录并统计病毒文件数量
• 隔离病毒文件到一个名为"Quarantine"的目录中
• 清理隔离目录并将文件恢复到原始目录
