| Season | y_true | y_pred |
| -------- | -------- | -------- |
| 201314 |<font color="red">1</font> | <font color="red">4</font> |
| 201314 |<font color="red">2</font> | <font color="red">3</font> |
| 201314 |<font color="red">3</font> | <font color="red">2</font> |
| 201314 | <font color="red">4</font> | <font color="red">1</font> |

| 201415 | <font color="blue">6</font> | <font color="blue">5</font> |

## groupby 計算

依照 不同 Season 分別使用 score1_func(y_true,y_pred)、score2_func(y_true,y_pred) 進行評分

| Season | score1 | score2 |
| -------- | -------- | -------- |
| 201314 | 2 | 0 |
| 201415 | 3 | 1 |

計算:
201314 的 score1 = score1_func(y_true=<font color="red">[1,2,3,4]</font>,y_pred=<font color="red">[4,3,2,1]</font>) = 2
201314 的 score2 = score2_func(y_true=<font color="red">[1,2,3,4]</font>,y_pred=<font color="red">[4,3,2,1]</font>) = 0
201415 的 score1 = score1_func(y_true=<font color="blue">[5,6]</font>,y_pred=<font color="blue">[6,5]</font>) = 3
201415 的 score2 = score2_func(y_true=<font color="blue">[5,6]</font>,y_pred=<font color="blue">[6,5]</font>) = 1

## 計算總分
Total Score = 2 + 0 +3 +1 = 6
