you can use format :

element = 'id_of_element'

js = """
var element = document.getElementById("{}")
""".format(element)

I found the solution -

You have to use a single quote around around the three double quotes

Like this -

element = 'id_of_element'
js = """
var element = document.getElementById('"""+element+"""')
"""
