Can I call a JavaScript function on an iFrame or similar widget from Python?

Question

I am trying to mix Python code with D3 vizualizations. Right now I have a bunch of D3 vizualizations and JavaScript functions. I have a couple different ways of embedding the D3, but what I want is to call a function that affects the vizualization AFTER I create it.

For example:

createD3Stuff()
for i in [0,1,2,3]:
    executeFunction(i)

Where createD3Stuff() generates the vizualization, and executeFunction does something on that vizualization, like creates an element with id=i.

Is this possible? How can I do it?

Background information: I am using Jupyter Notebooks, but if there is some other way to get this to work I can switch. I know how to do all the d3 and javascript stuff, it is just getting the python and javascript to interact that is giving me trouble.

Answer 1

Of course you can.

Just try this:

from IPython.display import HTML
HTML("<script>alert('hello world')</script>")
