问题描述

我能够显示和返回列表中的所有项目，但每个项目都在一个单独的列表中。

我想要的是将所有项目附加到一个列表中。我将感谢任何帮助实现我的目标。

我得到的结果：

there are 4

['C:/Users/test/Downloads\cv.docx']
['C:/Users/test/Downloads\cv.docx', 'C:/Users/test/Downloads\Volunteer Card.docx']
['C:/Users/test/Downloads\cv.docx', 'C:/Users/test/Downloads\Volunteer Card.docx', 'C:/Users/test/Downloads\insta maro\followers.docx']
['C:/Users/test/Downloads\cv.docx', 'C:/Users/test/Downloads\Volunteer Card.docx', 'C:/Users/test/Downloads\insta maro\followers.docx', 'C:/Users/test/Downloads\PdfToText-master\examples\text-capture\sample-report.doc']

上面的最后一行返回什么

到现在为止我做了什么
