The first O’Reilly book I ever purchased was “Sed & Awk”, and has been one of the most invaluable over the last 20 years. While they are not the simplest tools to master, they are worth the effort; especially when you are trying to do inline “one-liners” to massage data or process large files. That doesn’t mean it’s a requirement to know them, but it does get easier with practice. That said, if making a little python one-off filter to do what you need is faster (to write) and works (well enough), it comes down to what your time is worth. — David Rock da...@graniteweb.com _______________________________________________ Tutor maillist - Tutor@python.org To unsubscribe or change subscription options: https://mail.python.org/mailman/listinfo/tutor
