Open the help in a bottom panel

[jtpio]

The classic notebook (v6) opens the help panel at the bottom of the page, for example when using the following code snippet:

import math
math.pi?

JupyterLab inlines the help in the output:

Jupyter Notebook 7 does the same as JupyterLab since it uses the same notebook component:

Opening this issue to track this feature parity difference. Not sure this needs to be addressed for Notebook 7 but at least it's tracked somewhere.

In the classic notebook this is also called the "pager":

For reference this is handled here in JupyterLab:

https://github.com/jtpio/jupyterlab/blob/eeaa6505f658f7eaaad18ea2d7f15c3c5da0b23a/packages/outputarea/src/widget.ts#L664-L688

The content of the message contains "source": "page" as part of the payload:

{
  "content": {
    "status": "ok",
    "execution_count": 3,
    "user_expressions": {},
    "payload": [
      {
        "source": "page",
        "data": {
          "text/plain": "\u001b[0;31mType:\u001b[0m        float\n\u001b[0;31mString form:\u001b[0m 3.141592653589793\n\u001b[0;31mDocstring:\u001b[0m   Convert a string or number to a floating point number, if possible."
        },
        "start": 0
      }
    ]
  },
  "channel": "shell"
}

The "Messaging in Jupyter" documentation also has some information about page: https://jupyter-client.readthedocs.io/en/stable/messaging.html#payloads-deprecated

Pager output is used for introspection, or other displayed information that’s not considered output. Pager payloads are generally displayed in a separate pane, that can be viewed alongside code, and are not included in notebook documents.

It's not clear whether this will be addressed in time for 7.0. Bumping to 7.1, but if someone would like to have a look at it feel free to comment here!
