How to sort a list of strings in reverse order without using reverse=True parameter?

Question

I want to sort a list of strings in reverse order, e.g.:

my_list = [\'aaa\', \'bbb\', \'ccc\']

expected result:

[\'ccc\', \         


        

Answer 1

You can do a negative ord on the value and that would work for an ascii string:

>>> sorted(my_list2, key=lambda x: ([-ord(l) for l in x[0]], x[1]))
[('bbb', 'aaa'), ('bbb', 'ccc'), ('aaa', 'bbb'), ('aaa', 'ccc')]

For non-ascii though you'd have choices in how you'd want to sort though:

>>> sorted(my_list2, key=lambda x: ([-ord(l) for l in x[0]], x[1]))
[('ébb', 'écc'), ('bbb', 'aaa'), ('aaa', 'bbb'), ('aaa', 'ccc')]
