symbolic-constants

Extension of the StrEnum to class to enable some additional dictionary-like behaviour.

Usage

Subclass SymbolicConstant:

from symbolic_constants import SymbolicConstant

class MyConstant(SymbolicConstant):
    ATTRIBUTE1: "attribute 1"
    ATTRIBUTE2: "attribute 2"

Use as type hint in function definitions:

def foo(attr: MyConstant) -> MyConstant:
    ...

... or access the string literal directly:

a = foo(attr = MyConstant.ATTRIBUTE1)

Access all attributes in a dictionary like fashion:

MyConstant.values()

# Returns ['attribute 1', 'attribute 2']

MyConstant.keys()
# Returns ['ATTRIBUTE1', 'ATTRIBUTE2']

MyConstant.items()
# Returns [('ATTRIBUTE1', 'attribute 1'), ('ATTRIBUTE2', 'attribute 2')]
