mydict.items() is not a list - Skaperen - May-07-2020 what i get from mydict.items() is not a list. i can't .sort() it. it have to make a list from it to be able to sort it in-place, defeating the performance advantage of sorting in place. what can be done to have the list of items in sorted order with that kind of performance? RE: mydict.items() is not a list - perfringo - May-07-2020 One can sort dictionaries with sorted(), not in-place though: >>> d = {5: 'five', 3: 'three', 2: 'two'} >>> sorted(d) [2, 3, 5] >>> sorted(d.items()) [(2, 'two'), (3, 'three'), (5, 'five')] >>> dict(sorted(d.items())) {2: 'two', 3: 'three', 5: 'five'} RE: mydict.items() is not a list - DeaD_EyE - May-07-2020 Here is an example with itemgetter: https://python-forum.io/Thread-Sort-last?pid=113226#pid113226 This is useful, if you have a list with dicts and the dicts do have all the same keys. Sorting them with the key function together with itemgetter is very handy. |
