Enums are readable names that are bound to a constant value.
To use enums, import
Enum from the
enum standard library module:
from enum import Enum
Then you can initialize a new enum in this way:
class State(Enum): INACTIVE = 0 ACTIVE = 1
Once you do so, you can reference
State.ACTIVE, and they serve as constants.
Now if you try to print
State.ACTIVE for example:
it will not return
The same value can be reached by the number assigned in the enum:
print(State(1)) will return
State.ACTIVE. Same for using the square brackets notation
You can however get the value using
You can list all the possible values of an enum:
list(State) # [<State.INACTIVE: 0>, <State.ACTIVE: 1>]
You can count them:
len(State) # 2
