### 設定滑鼠按下時放置棋子
```python
if event.type == pygame.MOUSEBUTTONDOWN:
```
---
### 玩家選擇位置
#### 原本
```python
col = int(input("玩家1請選一個數字(0 ~ 6)"))
```
#### 修改後
```python
posx = event.pos[0]
col = int(math.floor(posx/SQUARESIZE))
```
---
### 獲勝字樣
#### 原本
```python
print("恭喜玩家1獲勝!!!")
```
#### 修改後
```python
label = myfont.render("Player 1 wins!!!", 1, RED)
screen.blit(label, (40, 10))
```
---
### 更新棋盤
- 每次放完棋子後都要更新一次棋盤和棋子
```python
print_board(board)
draw_board(board)
```
---
### 結束遊戲
```python
if game_over:
pygame.time.wait(3000)
```
