That is because the sage shell and notebook preprocess input such that integer literals are made into sage integers: sage: type(10) <type 'sage.rings.integer.Integer'> sage: type(int(10)) <type 'int'> sage: sum(x,x,1,int(10)) AttributeError: 'int' object has no attribute '_maxima_' -- 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 URL: http://www.sagemath.org
