使用Python的turtle畫炫酷圖形
例子一：
import turtle
t = turtle.Pen()
turtle.bgcolor("black")
sides=6
colors=["red","yellow","green","blue","orange","purple"]
for x in xrang(360):
t.pencolor(colors[x%sides])
t.forward(x*3/sides+x)
t.left(360/sides+1)
t.width(x*sides/200)
print("####結束####")
效果圖如下：
例子二：
可以做成交互的，利用eval函數獲得用戶想繪製的邊數
代碼：
#Python學習交流群：973783996
import turtle
t = turtle.Pen()
turtle.bgcolor("black")
sides=evali(input("輸入要繪製的邊的數目，請輸入2-6的數字！"))
colors=["red","yellow","green","blue","orange","purple"]
for x in xrange(100):
t.pencolor(colors[x%sides])
t.forward(x*3/sides+x)
t.left(360/sides+1)
t.width(x*sides/200)
print("####結束####")
效果：兩條邊
例子三：
繪製橡皮筋球體
import turtle
#Python學習交流群：973783996
t = turtle.Pen()
turtle.bgcolor("black")
#sides=evali(input("輸入要繪製的邊的數目，請輸入2-6的數字！"))
sides=6
colors=["red","yellow","green","blue","orange","purple"]
for x in range(360):
t.pencolor(colors[x%sides])
t.forward(x*3/sides+x)
t.left(360/sides+1)
t.width(x*sides/180)
t.left(91)
print("####結束####")
效果圖如下：
