Note that the documentation for region_plot (not plot_region, though that would be good to add as an alias) says we have to use a list to do multiple conditions, as in sage: region_plot([y>0, x>0], ...) and technically -1<x and x<1 are separate conditions. I know that doesn't answer the question of whether we *should* accept -1<x<1, but at any rate currently I don't think Sage accepts such things anywhere. Apparently currently the preparser ignores everything after the 'x'; I'm not sure what is going on syntactically, a Python expert will hopefully chime in. - kcrisman -- To post to this group, send an email to sage-devel@googlegroups.com To unsubscribe from this group, send an email to sage-devel+unsubscr...@googlegroups.com For more options, visit this group at http://groups.google.com/group/sage-devel URL: http://www.sagemath.org
