Hello again, I've found myself stumped when trying to organize this list of objects. The objects in question are timesheets which i'd like to sort by four attributes:
class TimeSheet: department = string engagement = string date = datetime.date stare_hour = datetime.time My ultimate goal is to have a list of this timesheet objects which are first sorted by departments, then within each department block of the list, have it organized by projects. Within each project block i finally want them sorted chronologically by date and time. To sort the strings i tried: timesheets.sort(key=operator.attrgetter('string')) which is not doing anything to my list unfortunately; it leaves it untouched. Giving up on that i tried to sort the dates or times using: def sorter_time(a,b): if a.engagement == engagement: # I only want sorting done within each engagement block return cmp(a.start, b.start) return 0 timesheets.sort(sorter_time) But this also did nothing to my list, and at this point i'm incredibly confused. From what i know of the involved functions, i would think that these lines of code (while they wouldn't do exactly what i want yet) would at least do something to my lists. Any explanations, or suggestions for a different approach would be greatly appreciated. My brain might explode if i continue. -- http://mail.python.org/mailman/listinfo/python-list
