烏龜繪圖背景改變raw_input python 2.7

Question

我想讓用戶輸入一個顏色名稱來設置烏龜窗口的背景，這是一個繪圖程序，我忘了該怎麼做呢？

import turtle 

wn = turtle.Screen() 


color = raw_input('enter background color') 

color ??????? wn.bgcolor('')  # set the window background color 




tess = turtle.Turtle() 
tess.color("blue")    # make tess blue 
tess.pensize(3)     # set the width of her pen 

tess.forward(50) 
tess.left(120) 
tess.forward(50) 

wn.exitonclick()    # wait for a user click on the canvas 

Answer 1

只要給字符串到bgcolor()方法：

... 
color = raw_input('Enter background color: ') 
wn.bgcolor(color) 
tess = turtle.Turtle() 
....
