hi there, this is probably just a silly Python question, but let me try. I've designed a little class that has a __add__() method, and it works fine for expressions like x+y. However, sum() does not work on a list of such objects ! do I need to do something else ? (in the meanwhile i go reduce(lambda x,y : x+y, list) which is cumbersome).
along the same lines, my class has a __str__() method, and 'print x' works. But 'print L' where L is a list of such objects does not work... any idea? thanks a lot! pierre --~--~---------~--~----~------------~-------~--~----~ To post to this group, send email to sage-support@googlegroups.com To unsubscribe from this group, send email to [EMAIL PROTECTED] For more options, visit this group at http://groups.google.com/group/sage-support URLs: http://www.sagemath.org -~----------~----~----~----~------~----~------~--~---
