在这篇文章中，我们来学习一下“Python实现批量解压加密压缩包的脚本是什么”的相关知识，下文有详细的讲解，易于大家学习和理解，有需要的朋友可以借鉴参考，下面就请大家跟着小编的思路一起来学习一下吧。

环境需求

• Windows系统
• Python 3
• 对于解压RAR文件，需要安装WinRAR
• 对于解压7z/zip等其他7-Zip支持解压的文件，需要安装7-Zip

用法 Usage

直接拖入文件夹或压缩文件即可批量解压缩包含密码的压缩文件。如果拖入的是文件夹，则会把该文件夹下的压缩文件解压缩，但不进入下一级目录。通过设置PASSWD来设置字典，通过设置DELETEIT来设置解压后是否删除被成功解压的压缩文件。本脚本会通过文件的后缀识别该文件是否为压缩文件。

你可以把WinRAR目录下的Unrar.exe和7-Zip目录下的7z.exe直接复制到这个toolUnRar.py文件的相同目录下，这样就可以携带使用了。

参数 Parameters

• PASSWD = ["hello","123456"] ：你的密码本，该脚本会从这个数组中不断试验密码来解压缩，直到成功为止。
• DELETEIT ：一个危险的参数。为真时，该脚本会直接删除成功解压的压缩文件。为假则不会删除。
• LOC_WINRAR = "C:\Program Files\WinRAR\" 你的WinRAR安装位置。就算这个变量的设置的不对，该程序也会在可能的位置来寻找对应的程序。
• LOC_7Z：7-Zip的安装位置。
• SAVE_MODE = True：如果该脚本无法通过后缀判断这是不是压缩文件，则不对该文件进行操作。
