你如何在Jupyter笔记本中包装线条？

Question

I have a Jupyter notebook that I wish to convert to pdf for publication, however when I save the notebook as a pdf many of the cells go over the edge.

Is there are way to wrap lines (to the standard 80 characters) so that as I type the cells are never wider than a standard A4 page?

Alternatively, is there something I can do when I convert to pdf instead? Thanks.

Here is a solution which will always wrap long lines (not just on export to psd):

https://stackoverflow.com/a/39398949/5411817

Essentially, there is a flag in Jupyter's config file which turns on line wrapping.

Simply add the following to your config:

{
  "MarkdownCell": {
    "cm_config": {
      "lineWrapping": true
    }
  },
  "CodeCell": {
    "cm_config": {
      "lineWrapping": true
    }
  }
}

You'll need to restart Jupyter to see the change.

You can find (or create) your config file in your user directory: ~/.ipython/profile_nbserver/ipython_notebook_config.py ,

My Bad: I did not realize that line wrapping breaks on export to PDF !! Comment under question by @Louie links to a discussion and sample code for writing a custom exporter . He also poses a workaround of manually wrapping long lines (in a pinch).

I'll leave my answer here, as it answers the question posted as the Title (" How do you wrap lines in a Jupiter Notebook? "), and highlights that the usual solution breaks on pdf export. Others looking for that answer can easily find it in this thread.
