You return it.  E.g.:

	def process(spam):
		"process spam and all sub-spams, and return a total"
		total = 0
		... do some processing that increments localTotal...
		... and now, for sub-spams:
		for subspam in subspams(spam):
			total = total + process(subspam)

		# all done!  return the grand total
		return total

See how the total is a sum of any local increments, plus all the 
totals of the sub-spams?

Cheers,
