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).
