不小心删除了我所有的 jupyter notebook 数据，仍然在 jupyter 变量中显示数据

Question

嗨，我不小心删除了我的 jupyterlab 笔记本数据我试图将数据从 ipynb 保存为 csv 格式我使用了命令：

path = ('F:\jupyter Lab Projects\Automotive residual value.ipynb')
df.to_csv(path)

在我执行命令后，我的 ipynb 笔记本中的所有内容都消失了，我试图通过执行 ctrl + z 来恢复命令，但什么也没发生但是我可以在位于终端部分右侧下方的 jupyter 变量部分中看到我的数据。 我正在使用 VSCODE 和 anaconda 库 如果有人知道如何恢复数据，请帮助我 我真的很努力地创建该数据。 提前致谢。

我试图通过按 ctrl+ z 来恢复命令，但没有任何反应

正如我之前告诉你的那样，数据显示在 jupyter 变量中，但不显示在笔记本中，所以晚上有机会恢复它，因为笔记本这里是笔记本的链接。

Answer 1

尝试将您的 dotepad 下载为.ipynb文件，然后在文本编辑器中将其作为文本文件查看（使用编辑器打开）。

使用它，我得到了那些值。 那是你需要的吗？：
