Again, this is very subjective, but this code would fail my code review :) Don't you find buf = [None] * get_size() my_func(arg, buffer=buf, size=len(buf)) to be more readable? IMHO this example is why we shouldn't implement any form of assignment expressions in Python :) Yury _______________________________________________ Python-Dev mailing list [email protected] https://mail.python.org/mailman/listinfo/python-dev Unsubscribe: https://mail.python.org/mailman/options/python-dev/archive%40mail-archive.com
