Python小豬佩奇來拜年

快要過年了，在這裏給大家帶來的是Python版的小豬佩奇拜年！
效果如下：

turtle庫介紹

turtle（海龜）庫是python自帶的繪圖庫，可以用它來繪製想要的圖畫。
它的繪圖原理：有一隻海龜，其實在窗體正中心，在畫布上游走， 走過的軌跡形成了繪製的圖形。海龜由程序控制，可以控制移動、變換 顏色、改變寬度等。

主要指令：

1. 控制指令
   
2. 繪製指令
   
3. 全局指令
   
   這些指令都比較簡單，利用這些指令，你就可以像一個畫家一樣，手握畫筆，開始你的創作了。

小豬佩奇拜大年

看過有人利用turtle花了叮噹貓、皮卡丘，感覺很有趣。恰逢過年，這次帶來的是用turtle繪製的小豬佩奇拜大年的源碼,祝大家新年快樂。
