Question

我从 self.fileSystemModel.fileInfo（index）.absoluteFilePath（）获取文件路径删除文件路径是有效的，但压缩它不...我单独尝试了邮政编码，它可以工作。

self.fileSystemModel.fileInfo（index）.absoluteFilePath（）提供的路径无法压缩...如何从QTreeView获取可以压缩的路径

这是我的代码

dpath错误...更改为用户目录...新代码

def zip_file(self,):
    dpath = r'C:\Users\Black Laptop\Desktop\DC.zip'
    if os.path.isfile(self.path):
        with ZipFile(dpath, 'w') as zip:
            zip.write(self.path, basename(self.path))

    else:
