（Turtle）🐢繪製Rose（🌹）
用Python繪製一朵玫瑰花（附源代碼）
要求：①電腦需配備Python3.xx的環境
②需要的模塊包 turtle(Python內置包）
Turtle（🐢）
個人接觸的第一個Python庫就是Turtle，業內Guido稱我們這類人爲：畫龜入門，也快過年了，學了這麼長時間的語言了，也該給自己另一個她拿程序寫個小東西，表達一下自己的愛慕之情，所以年前趕忙寫了這篇博客，希望闊以幫助大家，新年裏把這段代碼送給自己的另一個她，不要再讓外面傳程序員不懂浪漫熬，證明自己，程序員的浪漫是俗人無法理解的，奧裏給！
先讓你們酸一下，上一張成品圖
好不好看，觀衆姥爺說了算。
此圖應該是全網拿Python繪製最好看玫瑰花，自信一點說，自己動手翻閱博客，目前沒有找到闊以與之媲美的，當然好看是需要代價的，繁瑣的循環，500+行的代碼，計算起來，複雜程度不用我多說，所以個人推薦：Copy走自己玩一玩發給另一個她，儘量不要自己動手瞧;當然如果有鐵子想表達一下對另一個她的真心，闊以親自動手敲一遍。
完整源代碼
#套用的循環我已放入Shell命令行供大家參考改進。

是不是讓繁雜的代碼整懵了，哈哈哈，總的來說就是不斷套用循環的思路去繪製，只是其中用到的數學知識比較多，所以吶，小夥伴們如果想玩轉Turtle庫得好好溫習下自己的數學嘍。
