This is actually a case where style guidelines would ideally differ between between scripting use cases (let the GC handle it whenever, since your process will be terminating soon anyway) and library(/framework/application) development use cases (promptly clean up after yourself, since you don't necessarily know your context of use). However, that script/library distinction isn't well-defined in computing instruction in general, and most published style guides are written by library/framework/application developers, so students and folks doing ad hoc scripting tend to be the recipients of a lot of well-meaning advice that isn't actually appropriate for them :( Cheers, Nick. -- Nick Coghlan | ncogh...@gmail.com | Brisbane, Australia _______________________________________________ Python-ideas mailing list Python-ideas@python.org https://mail.python.org/mailman/listinfo/python-ideas Code of Conduct: http://python.org/psf/codeofconduct/
