:-) Extension: if you used [] in the format string, the results would be tuples. :-) > Hmmm, maybe that's > worth a PEP? Great minds think more-or-less alike :-) All we need now is for the populace to vote on "least fugly syntax". Yours has the advantage over mine that it would handle (say) 10(4s) *if* anybody ever wanted to do that, but the ")" is a redundant nuisance. Mine could be changed so that the "/" is between the count and the format code, so that 10/4s would work ... hmmm there are actually 3 different numbers: an overall repeat count, a tuple/list length, and a field width. The current syntax uses the one number as a field width for "s" and as a repeat count for other format codes. Ugh. BTW the only reason I picked "/" was it doesn't need the Shift key :-) Cheers, John -- http://mail.python.org/mailman/listinfo/python-list
