Thank you #J #APL. I cannot think of a cleaner way of expressing this logic.

options_specified = [1 for x in [args.username, args.email, args.id] if x]
number_of_options_given = sum(options_specified)
if number_of_options_given > 1:
LOG.error(...)

@vertigo is this Python? How do you feel about sum(map(bool, [args.username, …]))?

@vertigo It's a _little_ weird that in Python, (True + True == 2), but it sure can be convenient on occasion!
