画迷宫的代码

import turtle

def draw_square(t,a,c):
    t.color(c)
    t.pencolor("black")
    t.begin_fill()
    for i in range(4):
        t.forward(a)
        t.left(90)
    t.end_fill()


def locate(t):
    t.up()
    t.fd(10)
    t.left(90)
    t.fd(10)
    t.right(90)
    t.down()


turtle.setup(500,500,200,200)
t=turtle.Pen() #这个Pen 第一个字母要大写。
t.up()
t.fd(-150)
t.right(90)
t.fd(150)
t.left(90)
t.down()
a=300
t.pensize(5)

for i in range(5):
    draw_square(t,a,"red")
    a=a-20
    locate(t)
    draw_square(t,a,"yellow")
    a=a-20
    locate(t)
    draw_square(t,a,"blue")
    a=a-20
    locate(t)

效果如下：
