A enum library for Python.
- enum
- A simple enum implementation that maps a "variable" to a constant.
- RichEnum
- An enum implementation that offers more functionality than a basic enum, hence the name: RichEnum. Provided functionality include specifying a canonical name and a display name. The canonical name should be used if you need to do a lookup or reference in your code. The display name should be used if you need to display text to a user.
- OrderedRichEnum
- Exactly like RichEnum but also has an index specified for each enum value. Also, iteration over an OrderedRichEnum will be sorted (ascending) by the enum value's index.
$ pip install richenum>>> from richenum import enum
>>> MY_ENUM = enum(FOO=1, BAR=2)
>>> MY_ENUM.FOO
1
>>> MY_ENUM.BAR
2>>> from richenum import RichEnum, RichEnumValue
>>> class MyRichEnum(RichEnum):
... FOO = RichEnumValue(canonical_name="foo", display_name="Foo")
... BAR = RichEnumValue(canonical_name="bar", display_name="Bar")
...
>>> MyRichEnum.FOO
RichEnumValue - canonical_name: 'foo' display_name: 'Foo'
>>> MyRichEnum.from_canonical("foo")
RichEnumValue - canonical_name: 'foo' display_name: 'Foo'>>> from richenum import OrderedRichEnum, OrderedRichEnumValue
>>> class MyOrderedRichEnum(OrderedRichEnum):
... FOO = OrderedRichEnumValue(index=1, canonical_name="foo", display_name="Foo")
... BAR = OrderedRichEnumValue(index=2, canonical_name="bar", display_name="Bar")
...
>>> MyOrderedRichEnum.FOO
OrderedRichEnumValue - idx: 1 canonical_name: 'foo' display_name: 'Foo'
>>> MyOrderedRichEnum.from_canonical("foo")
OrderedRichEnumValue - idx: 1 canonical_name: 'foo' display_name: 'Foo'
>>> MyOrderedRichEnum.from_index(1)
OrderedRichEnumValue - idx: 1 canonical_name: 'foo' display_name: 'Foo'- django-richenum
