* list.sort() now supports three keyword arguments: cmp, key, and reverse.
key provides C support for the decorate-sort-undecorate pattern.
reverse provide a stable sort of the list with the comparisions reversed.
* Amended the docs to guarantee sort stability.

Core and builtins ----------------- +- list.sort() now supports three keyword arguments: cmp, key, and reverse. + The key argument can be a function of one argument that extracts a + comparison key from the original record: mylist.sort(key=str.lower). + The reverse argument is a boolean value and if True will change the + sort order as if the comparison arguments were reversed. In addition, + the documentation has been amended to provide a guarantee that all sorts + starting with Py2.3 are guaranteed to be stable (the relative order of + records with equal keys is unchanged). + - Added test whether wchar_t is signed or not. A signed wchar_t is not usable as internal unicode type base for Py_UNICODE since the unicode implementation assumes an unsigned type. |
