我有代码都能够一次输入一个字母，但由于某种原因无法弄清楚如何使它所以用户最多可以输入三个字母供龟绘制。这是我的代码到目前为止。任何帮助将不胜感激，提前谢谢需要用户最多可以输入三个字母，一次为蟒蛇绘制

不知道发生了什么事情，'turtle.textinput（）'让我尽可能多地输入我想要的字母，甚至是非字母字符。 – Goyo

我可以输入尽可能多的字母，乌龟只是不画他们 –

也许这是因为你一次输入多个字母。然后你的程序检查是否e。 G。 “ABC”匹配“A”。尝试输入单个字母。

由于您的字母相对于原点（0，0）打印，技巧是将屏幕分成几部分（比如三分之一），对于每个字母，在绘制字母之前移动到相应部分的中心。

我重新编写了下面的代码来完成上述操作（最多三个字母）并简化了一些逻辑。信功能本身是不变的，所以我离开了大头他们的下面，只是在拼接你原来的代码有：

from turtle import Turtle, Screen 

SCREEN_WIDTH, SCREEN_HEIGHT = 1200, 600 
SCREEN_MARGIN = 0.1 * SCREEN_WIDTH 
MAXIMUM_CHARACTERS = 3 
CHARACTER_WIDTH = (SCREEN_WIDTH - (2 * SCREEN_MARGIN))/MAXIMUM_CHARACTERS 
COLORS = ['purple', 'blue', 'black'] 

velcro = Turtle() 
screen = Screen() 

def letter_A(): 
    velcro.left(90) 
    velcro.forward(150) 
    velcro.right(90) 
    velcro.forward(150)

    velcro.forward(150)

    velcro.forward(75) 
    velcro.left(90) 
    velcro.forward(150)

def letter_Z():

    velcro.left(140) 
    velcro.forward(300) 
    velcro.right(140) 
    velcro.forward(225) 

letter_lookup = { 
    'A': letter_A, 
    'B': letter_B, 
    'C': letter_C, 
    'D': letter_D, 
    'E': letter_E,

    'W': letter_W, 
    'X': letter_X,

} 

screen.setup(width=SCREEN_WIDTH, height=SCREEN_HEIGHT)

if (velcroColor in COLORS): 
    velcro.color(velcroColor) 

velcroLetters = screen.textinput("Turtle alphabet", "Please enter up to 3 letters from A-Z to draw:")[:MAXIMUM_CHARACTERS] 

center_x = CHARACTER_WIDTH * (len(velcroLetters) - 1)/-2 

for letter in velcroLetters: 
    velcro.penup() 
    velcro.home() 
    velcro.goto(center_x, 0) 
    velcro.pendown() 
    letter_lookup[letter.upper()]() 

    center_x += CHARACTER_WIDTH 

screen.mainloop()
