net-test: be more compatible with python3, part 2
and fix a couple of very minor bugs in the first part of the conversion
- print() prints () on python2 (unlike py3 where it prints an empty line)
- similarly print(a,b) prints (a,b) on py2 (unlike py3 where it prints 'a b\n')
- there doesn't seem to be a good way to get print without trailing newline
behaviour that works with both py2 and py3 without falling back to
sys.stdout.write()
