使用Python画了一棵圣诞树的实例代码
import turtle
screen = turtle.Screen()
screen.setup(375, 700)
circle = turtle.Turtle()
circle.shape('circle')
circle.color('red')
circle.speed('fastest')
circle.up()
square = turtle.Turtle()
square.shape('square')
square.color('green')
square.speed('fastest')
square.up()
circle.goto(0, 280)
circle.stamp()
k = 0
for i in range(1, 13):
y = 30 * i
for j in range(i - k):
x = 30 * j
square.goto(x, -y + 280)
square.stamp()
square.goto(-x, -y + 280)
square.stamp()
if i % 4 == 0:
x = 30 * (j + 1)
circle.color('red')
circle.goto(-x, -y + 280)
circle.stamp()
circle.goto(x, -y + 280)
circle.stamp()
k += 3
if i % 4 == 3:
x = 30 * (j + 1)
circle.color('yellow')
circle.goto(-x, -y + 280)
circle.stamp()
circle.goto(x, -y + 280)
circle.stamp()
square.color('brown')
for i in range(13, 17):
y = 30 * i
for j in range(2):
x = 30 * j
square.goto(x, -y + 280)
square.stamp()
square.goto(-x, -y + 280)
square.stamp()
