The default is that a sorts before b if a < b. So what you actually want to know is how strings compare to one another, and the answer from the Python 3 documentation is: "Strings are compared lexicographically using the numeric equivalents (the result of the built-in function ord()<http://docs.python.org/3/library/functions.html#ord>) of their characters." If you want to sort according to a specific locale, use the locale.strxfrm key function: sorted_strings = sorted(original_strings, key=locale.strxfrm)
