rar文件处理

1.下载UnRAR.exe，与python文件放在同一目录下

2.使用rarfile模块

代码：

    def rar_f(self, fz_name, path):
         """
        解压缩文件
        :param fz_name: zip文件
        :param path: 解压缩路径
        :return:
        """

         flag = False
         try:
             if rarfile.is_rarfile(fz_name): # 检查是否为rar文件
                 rf = rarfile.RarFile(fz_name) # 待解压文件
                 rf.extractall(path)
                 # print(
                 #     "%s is running [%s] " %
                 #     (currentThread().getName(), fz_name))
                 print('解压缩文件[{}]成功'.format(fz_name))
             flag = True
         except Exception as e:
             print('解压缩文件[{}]失败'.format(fz_name), str(e))
         return {'file_name': fz_name, 'flag': flag}

 rar_f('F:\test\2019.rar','F:\test')
