You mean kinda like (untested):
l = map(lambda c: c, s)
l.reverse()
i = 0
ret = ''
for ch in l:
if i and not i % 3:
ret = ',' + ret
ret = ch + ret
i += 1
Don't need a second reverse, but it doesn't help much. Maybe it's too
much cold symptom suppressor (or not enough?), but this is making me
feel stupid (more so than usual).
