expand_more The difference between sort and sorted in Python is that while list.sort(~) permanently modifies the order of the original list, sorted(~) returns your list in a sorted order but does not actually modify the original list.
sort method
To permanently modify order of elements in animals according to reverse alphabetical order:
animals = ['cat', 'doge', 'bird']print("Using sort: ", animals.sort(reverse=True))print("Original list: ", animals)
Using sort: NoneOriginal list: ['doge', 'cat', 'bird']
Notice that nothing is returned from animals.sort(reverse=True). However, the order of elements in the original list is modified.
sorted method
To return the list animals in reverse alphabetical order:
animals = ['cat', 'doge', 'bird']print("Using sorted: ", sorted(animals, reverse=True))print("Original list: ", animals)
Using sorted: ['doge', 'cat', 'bird']Original list: ['cat', 'doge', 'bird']
Notice that sorted(animals, reverse=True) returns the sorted list. However, the original list is unmodified.
