Just FYI, according to the python docs (http://docs.python.org/reference/expressions.html#notin), the "<>" is considered obsolescent. They encourage using "!=" instead. It looks like "<>" is not valid in 3.0, according to http://docs.python.org/3.1/reference/expressions.html#notin Jason -- Jason Grout --~--~---------~--~----~------------~-------~--~----~ To post to this group, send email to sage-support@googlegroups.com To unsubscribe from this group, send email to sage-support-unsubscr...@googlegroups.com For more options, visit this group at http://groups.google.com/group/sage-support URLs: http://www.sagemath.org -~----------~----~----~----~------~----~------~--~---
