be careful: >>> a = [1, 0, -1] >>> if a: print "true" true >>> if sum(a) != 0: print "true" that's why it's probably safer and more readable to use any() and all(), which i believe were both introduced to __builtin__ in py2.5. - d _______________________________________________ Edu-sig mailing list Edu-sig@python.org http://mail.python.org/mailman/listinfo/edu-sig
