Pass a variable in IPython / Jupyter to a block of html (%%html)

Question

I would like to pass a simple variable to an html cell on Jupyter:

cell 1:

a=5

cell 2:

%%html
<html>
  <head>
    <script type="text/javascript">
    window.alert(a);
    </script>
  </head>
</html>

This will return an error:

Javascript error adding output!
ReferenceError: a is not defined
See your browser Javascript console for more details.

This is a hacky solution:

a=5

html_code ="""
<html>
  <head>
    <script type="text/javascript">
    window.alert(%s);
    </script>
  </head>
</html>""" % a

from IPython.display import HTML
HTML(html_code)
