What’s the best way to implement an ‘enum’ in Python?
What is the Python idiom for a list of differently indexed names (like Enum in C/C++ or Java)?
Clarification: I want a property of a value to be set to a restricted range, such as card suites Heart, Club, Spade, Diamond. I could represent it with an int in range 0..3, but it would allow out of range input (like 15).

The enums are evaluatable string representation of an object also called repr(). The name of the enum is displayed using 'name' keyword. Using type() we can check the enum types.
Two enum names can have same value. For example, in the following C program both 'Failed' and 'Freezed' have same value 0.
By definition, the enumeration member values are unique. However, you can create different member names with the same values.
Enum names are in global scope, they need to be unique.
class Suite(object): pass class Heart(Suite): pass class Club(Suite): pass etc.
A class in python is an object. So you can write
x=Heart etc.

Edit:
class Suite(set): def __getattr__(self, name): if name in self: return name raise AttributeError s1 = Suite(['Heart', 'Club', 'Spade', 'Diamond']) s1.Heart If you love us? You can donate to us via Paypal or buy me a coffee so we can maintain and grow! Thank you!
