Write a custom filter that takes "spam" as an argument and does the
lookup for you.

The general plan is to either (a) write a custom template filter to do
this (similar to the last case and use forloop.counter as the argument)
or (b) stop trying to programming in templates and do programming in
your views instead. Arrange the datastructures that are passed to the
templates so that you can retrieve all the data value in a single loop.
Zip the lists together, or write a function that returns the
corresponding elements via an iterator and loop over that.
Django doesn't provide indirect variable references out of the box
intentionally.
