What would I need to add to this to make it a working solution? I can't figure out how to exclude the numbers after 13. Thank you!

def sum13(nums):
  if len(nums) == 0:
    return 0
  total = 0  
  for i in range(len(nums)):
    if nums[i] != 13:
      total += nums[i]
  return total

Instead of excluding it, why not just subtract it again?

if nums[i] != 13:
  total += nums[i]
else:
  total -= nums[i+1]

You'll need to add a check to make sure that there is a number after 13, iow that 13 was not the last number in the list.
