May 13, 2020 · To summarize, in this post we discussed how to sort objects in python. First we showed how to sort objects corresponding to instances of the ‘AppleMusicUser’ class according to the attribute ‘apple_id’ using the sorted method and a lambda function. Next, we showed how to perform the same sorting task by using the ‘attrgetter’ method ...
To sort the list in place... ut.sort(key=lambda x: x.count, reverse=True) # To return a new list, use the sorted() built-in function... newlist = sorted(ut, ...

The second sort accesses each object only once to extract its count value, and then it performs a simple numerical sort which is highly optimized. A more fair comparison would be longList2.sort(cmp = cmp). I tried this out and it performed nearly the same as .sort(). (Also: note that the "cmp" sort parameter was removed in Python 3.) –
Call sorted(iterable, key: NoneType=None) with a list of objects as iterable . For key , use operator.attrgetter(attr) with the name of the attribute to sort by ...
