![]() PFB the Python Wiki for sorting, do checkout other cool features of sorted() like specifying sorting type (Reverse Sorting), specifying keys etc. In python, to s ort list of tuples by the first element in descending order, we have to use the sort () method with the parameter (reverseTrue) which will sort the elements in descending order. Per the Python wiki inputList.sort() is more efficient, so consider that too while choosing your sorting mechanism. This function takes an iterable item and sorts the elements by a given key. So, something like for i,elt in enumerate(inputList.sort()) will fail, because inputList.sort() will return a None ,whereas for i,elt in enumerate(sorted(inputList)) will work fine.Īlso, sorted() works on all iterables whereas list.sort() is a method defined only for lists. Python comes with a function, sorted (), built-in. Sorted(inputList) on the other hand returns a new copy of the list in sorted order.Īnother important difference is that inputList.sort() returns None whereas sorted(inputList) returns a new list object. sort orders a list in place it uses Python standard comparison tests and by default sorts in. Well, inputList.sort()sorts the list in place, in other words, you loose the original list because it will be mutated to contain the new sorted list. Pythons sort() method makes it relatively easy to sort a list. The sorted() built-in returns a view (not a list) that is ordered. The 2 common ways to sort a list in Python are inputList.sort() or sorted(inputList). To perform sorting in Python, we use built-in methods.
