python怎么在turtle写字_使用turtle在Python中绘制输入

让我们扩展(并纠正)@GerardAnthonyMcBride基于字典的方法。下面是一个过于简化的示例，只打印字母“s”和“O”：from turtle import Turtle, Screen

SIZE = 100

def draw_O(turtle):

turtle.pendown()

for _ in range(4):

turtle.forward(SIZE)

turtle.left(90)

turtle.penup()

def draw_S(turtle):

position = turtle.position()

turtle.pendown()

turtle.forward(SIZE)

turtle.left(90)

turtle.forward(SIZE / 2)

turtle.left(90)

turtle.forward(SIZE)

turtle.right(90)

turtle.forward(SIZE / 2)

turtle.right(90)

turtle.forward(SIZE)

# leave turtle as we found it

turtle.penup()

turtle.setposition(position)

characters = {

‘O’: draw_O,

‘S’: draw_S,

}

screen = Screen()

yertle = Turtle()

string = input()

for character in string:

if character in characters:

characters[character](yertle)

yertle.forward(SIZE * 1.25)

screen.exitonclick()

输出
