Python自定義狀態碼枚舉類

在Java裏很容易作到自定義有狀態碼和狀態說明的枚舉類例如：

public enum MyStatus {
  NOT_FOUND(404, "Required resource is not found");

  private final int code;
  private final String msg;

  private MyStatus (int code, String msg) {
    this.code= code;
    this.msg = msg;
  }

  public int getCode() {
    return this.code;
  }

  public String getMsg() {
    return this.msg;
  }

   public static String getMsgByCode(int code){
        for(MyStatus status: MyStatus.values()){
            if(status.getCode() == code){
                return status.message;
            }
        }
        return null;
    }

}

可是在Python裏沒找到相似的能夠這樣作的方法，因而就利用了字典，不知道對不對，因此貼出來供參考和改進：
