IPython - Run all cells below from a widget

Question

I'm trying use a multi select widget to enable users to select from a list of countries, and then have a widget button which, when clicked, runs all the cells below.

This displays the list.

from IPython.display import display
w = widgets.SelectMultiple(

    description="Select up to five countries",
    options=dfCountries['name'].tolist()   
)
display(w)

And I want something like this to run all cells below:

def run_all(button):
    get_ipython().run_cell()

button = widgets.Button(description="Create next input")
button.on_click(run_all)
display(button)

But I can't find the hook to 'run all cells below

Thanks

Answer 1

If I understood correctly you could do that via js.

See the following code:

from IPython.display import Javascript
Javascript('IPython.notebook.execute_cells_below()')

Will execute all the cells below the active cell so for you button it could be something like:

from IPython.display import Javascript, display
from ipywidgets import widgets

def run_all(ev):
    display(Javascript('IPython.notebook.execute_cells_below()'))

button = widgets.Button(description="Create next input")
button.on_click(run_all)
display(button)

Let me know if this is what you need.
