Let me be the first of many to post a one liner: sage: def partition(v, n): ... return [v[n*i:n*i+n] for i in range(len(v)//n)] sage: partition([1,2,3,4],2) [[1, 2], [3, 4]] --~--~---------~--~----~------------~-------~--~----~ To post to this group, send email to sage-devel@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-devel URLs: http://www.sagemath.org -~----------~----~----~----~------~----~------~--~---
