如何从列表中的值更改乌龟的笔颜色？

Question

I have a list of numbers that the turtle draws, but I want the pen color to change based upon the value of the number in the list.

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)

Just using 5 as an example, is there a way to change the color based on the value of an element in the list?

I'm a bit new to Python, so thank you for any help in advance.

You can change a turtle's color by accessing it's .color method, if it's only the pen color you want to change, you can replace .color with .pencolor :

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

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

Or better yet, use enumerate :

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