But how does this handle language specific sorting rules  Does it take locale into account    No  list sort   is a generic sorting function  If you want to sort according to the Unicode rules  you ll have to define a custom sort key function  You can try using the pyuca module  but I don t know how complete it is

Old question  but if you want to do locale-aware sorting without setting locale LC ALL you can do so by using the PyICU library as suggested by this answer   import icu   PyICU  def sorted strings strings  locale None       if locale is None         return sorted strings      collator   icu Collator createInstance icu Locale locale       return sorted strings  key collator getSortKey    Then call with e g    new list   sorted strings list of strings   de DE utf8     This worked for me without installing any locales or changing other system settings    This was already suggested in a comment above  but I wanted to give it more prominence  because I missed it myself at first

The proper way to sort strings is   import locale locale setlocale locale LC ALL   en US UTF-8     vary depending on your lang locale assert sorted  u Ab   u ad   u aa    cmp locale strcoll      u aa   u Ab   u ad      Without using locale strcoll you get  assert sorted  u Ab   u ad   u aa        u Ab   u aa   u ad     The previous example of mylist sort key lambda x  x lower    will work fine for ASCII-only contexts

Basic answer   mylist     b    C    A   mylist sort     This modifies your original list  i e  sorts in-place   To get a sorted copy of the list  without changing the original  use the sorted   function   for x in sorted mylist       print x   However  the examples above are a bit naive  because they don t take locale into account  and perform a case-sensitive sorting  You can take advantage of the optional parameter key to specify custom sorting order  the alternative  using cmp  is a deprecated solution  as it has to be evaluated multiple times - key is only computed once per element    So  to sort according to the current locale  taking language-specific rules into account  cmp to key is a helper function from functools    sorted mylist  key cmp to key locale strcoll     And finally  if you need  you can specify a custom locale for sorting   import locale locale setlocale locale LC ALL   en US UTF-8     vary depending on your lang locale assert sorted  u Ab   u ad   u aa      key cmp to key locale strcoll       u aa   u Ab   u ad     Last note  you will see examples of case-insensitive sorting which use the lower   method - those are incorrect  because they work only for the ASCII subset of characters  Those two are wrong for any non-English data     this is incorrect  mylist sort key lambda x  x lower      alternative notation  a bit faster  but still wrong mylist sort key str lower

It is also worth noting the sorted   function   for x in sorted list       print x   This returns a new  sorted version of a list without changing the original list
