Exercise: Recursive Ticket Sum

The demo counted down by one; this time a box holds a short list of ticket bundles. Sum the first bundle and ask the same function to sum the remainder. The empty list is the base case, and bundles[1:] shrinks the problem each time. Only use small lists here; a normal loop is clearer for large inputs.

Edit main.py, Run for the sample total, then Submit. The function name and print are supplied.

Your Task

  1. Complete bundle_total(bundles) recursively: return 0 for an empty list; otherwise return the first number plus bundle_total(bundles[1:]).
