How to create and display 2 lists with 1 object in html?

Question

Django

I don't know how to display two lists with 1 object in html. I used to display 2 different ones, but I realized that this is not effective.
Tell me how this can be implemented?
Did something like this:

args = {}
args.update(csrf(request))
args['b'] = ('1', '2', '3')
args['a'] = ('a', 'b', 'c')
return render_to_response('one.html', args)

Answer 1

Implemented in this way.
If there is a more relevant option, I will be grateful)

Answer 2

Use itertools.chain()

import itertools
list_c = itertools.chain(list_a, list_b)
