Programmatically Create Jupyter Cells?

[Michael Zombok]

Hi,

I have a function which produces markdown output. Is there a way in Jupyter to programmatically create a markdown cell with the output of this function/a previous code cell?

Thanks!

Best,

Michael

Hi,

I've done this before by creating the cell using javascript.

Here is the function I used:

from IPython.display import display_javascript

def make_cell(s):

    display_javascript("""var t_cell = IPython.notebook.get_selected_cell()
    t_cell.set_text('<!--\\n' + t_cell.get_text() + '\\n--> \\n{}');
    var t_index = IPython.notebook.get_cells().indexOf(t_cell);
    IPython.notebook.to_markdown(t_index);
    IPython.notebook.get_cell(t_index).render();""".format(s.replace('\n','\\n')), raw=True)

You could replace 

I'm sure there are better ways to do this, but that worked for me.

Sorry, I meant to say you could replace "Jupyter.notebook.get_selected_cell()" with "Jupyter.notebook.inset_cell_below()" to create a new cell, rather than replacing the existing one.

Best wishes,

Josiah

Hi,

`get_selected_cell` has the problem that it's different depending
whether you have pressed `shift+enter` or `strg+enter` (or even
clicked somewhere completely different while the kernel computed the
output?).

Unfortunately, I know of no way to get the "source" of the current
appended output. If anybody has a workaround for that, I would love to
hear it :-)

If you want to append python code, you can use
`get_ipython().set_next_input('print "test"')`, which knows about the
source cell: https://github.com/jupyter/notebook/blob/master/notebook/static/notebook/js/notebook.js#L197-L210
