I'm trying to figure out a couple of cell operations

[paddymul]

I work on a widget that does DataFrame visualization and codegen. I want the widget to be able create a cell immediately below it, and inject then edit code in that cell.

I want to create a new cell, then get a reference to that created cell (by id or something else) then be able to edit that cell.

I have found a code snippet to edit a cell, but I don't know how to edit a cell, or find the cell I just created.

from IPython.core.getipython import get_ipython

def create_new_cell(contents):
    shell = get_ipython()
    payload = dict(
        source='set_next_input',
        text=contents,
        replace=False,
    )
    return shell.payload_manager.write_payload(payload, single=False)

I have reviewed the docs here, and I don't obviously see how to do this? https://jupyter-client.readthedocs.io/en/latest/messaging.html

Any suggestions?

jupyter-client doesn't know anything about notebooks. You can probably do that using JupyterLab's notebook API.

Thank you. There are so many packages around jupyter that it's not obvious where to search for code or even help.
