It’s recommended to switch to the [[ syntax anyways, some people consider [ deprecated. Also, [ is actually /bin/[ while [[ lives in your shell (and is therefore faster). About the equals sign, == is the preferred syntax, and = is also considered deprecated (zsh explicitly says so, bash says “only for POSIX compatibility”. -- Chris “Kwpolska” Warrick <http://chriswarrick.com/> PGP: 5EAAEA16 stop html mail | always bottom-post | only UTF-8 makes sense _______________________________________________ Tutor maillist - Tutor@python.org To unsubscribe or change subscription options: https://mail.python.org/mailman/listinfo/tutor
