Howdy all, I've uploaded enum 0.4 to the Cheeseshop. <URL:http://cheeseshop.python.org/pypi/enum/> Main changes: Comparing values from an enumeration against a value not from the same enumeration will now succeed (previous versions raised an exception):: >>> from enum import Enum >>> Weekdays = Enum('sun', 'mon', 'tue', 'wed', 'thu', 'fri', 'sat') >>> pizza_night = Weekdays.fri >>> pizza_night == Weekdays.fri True >>> pizza_night == Weekdays.tue False >>> pizza_night == "fri" False >>> pizza_night == 5 False This is done by using the ``NotImplemented`` return value for the comparison against values that are not from the same enumeration. The Python interpreter will then attempt other fallbacks instead of failing. This allows the values from an enumeration to be sequenced or compared among heterogeneous values, such as a list:: >>> things = [23, Weekdays.tue, "spam"] >>> things.sort() >>> Weekdays.tue in things True >>> Weekdays.fri in things False Package description: """Robust enumerated type support in Python This package provides a module for robust enumerations in Python. An enumeration object is created with a sequence of string arguments to the Enum() constructor:: >>> from enum import Enum >>> Colours = Enum('red', 'blue', 'green') >>> Weekdays = Enum('mon', 'tue', 'wed', 'thu', 'fri', 'sat', 'sun') The return value is an immutable sequence object with a value for each of the string arguments. Each value is also available as an attribute named from the corresponding string argument:: >>> pizza_night = Weekdays[4] >>> shirt_colour = Colours.green The values are constants that can be compared only with values from the same enumeration; comparison with other values will invoke Python's fallback comparisons. >>> pizza_night == Weekdays.fri True >>> shirt_colour > Colours.red True >>> shirt_colour == "green" False Each value from an enumeration exports its sequence index as an integer, and can be coerced to a simple string matching the original arguments used to create the enumeration:: >>> str(pizza_night) 'fri' >>> shirt_colour.index 2 """ -- \ "It ain't so much the things we don't know that get us in | `\ trouble.
