Jupyter Notebook, Python: How to call a magic from within a function?

Question

I am using the Jupyter Notebook, and am trying to create a widget, based on a template found on Github.

The template uses at some point the magic %%javascript<

Answer 1

If you use the ? IPython builtin, you can see the path for the magics. For example, %%javascript? shows that it is in lib\site-packages\ipython\core\magics\display.py

You can then just import it and use it as standard; for example, the following pops up an alert box if you run it from a notebook:

from IPython.core.magics.display import Javascript
Javascript('alert("hello world")')

EDIT: To get the example you posted in the comments working, just wrap the Javascript you'd like to run in quotes and call it with Javascript. Replacing In[4] with this pops out the window as normal and should be fine to include in a normal Python function.

from IPython.core.magics.display import Javascript
Javascript("""$('div.inspector')
    .detach()
    .prependTo($('body'))
    .css({
        'z-index': 999, 
        position: 'fixed',
        'box-shadow': '5px 5px 12px -3px black',
        opacity: 0.9
    })
    .draggable();""")
