from enum import Enum, auto class Direction(Enum): UP = auto() # 1 RIGHT = auto() # 2 DOWN = auto() # 3 LEFT = auto() # 4 def main(): print(Direction.RIGHT) # Direction.RIGHT print(Direction.RIGHT.value) # 2 (as int) print(Direction.RIGHT.name) # "RIGHT" value: Direction = Direction.DOWN print(value) # Direction.DOWN	import std.stdio; import std.conv; enum Direction { up = 1, right, // 2 down, // 3 left // 4 } void main() { writeln(Direction.right); // right writeln(int(Direction.right)); // 2 (as int) writeln(Direction.right.to!string); // "right" Direction value = Direction.down; writeln(value); // down }

Note: In D, for up we gave an explicit initial value (up = 1). If no initial value is given, then the default initial value would be 0.
