如何根据列表中的值更改海龟笔的颜色？

Question

我有一个乌龟绘制的数字列表，但我希望笔的颜色根据列表中数字的值而改变。

colors = ["red", "orange", "green", "cyan", "blue", "purple", "magenta", "pink"]

digits = map(int,str(5))

for number in digits:
    *code to change pen color to value of "index(number)" (in this case purple)*
    t.right(number*10)

以5为例，有没有办法根据列表中元素的值改变颜色？

我对 Python 有点陌生，所以感谢您提前提供的帮助。

你可以通过访问它的 .color 方法来改变乌龟的颜色，如果你只是想改变笔的颜色，你可以用 .pencolor 替换 .color:

colors = ["red", "orange", "green", "cyan", "blue", "purple", "magenta", "pink"]

for number in range(5):
    t.color(colors[number])
    t.right(number*10)

或者更好的是，使用 enumerate:

colors = ["red", "orange", "green", "cyan", "blue", "purple", "magenta", "pink"]
for number, color in enumerate(colors):
    t.color(color)
    t.right(number*10)
