前言
一年一度的圣诞节马上就要到了,看到朋友圈好多小伙伴已经开始炫耀自己制作的圣诞树了。今天给大家分享通过Pythoy用Turtle库来画圣诞树。(复制即可使用)
Turtle库是Python语言中一个很流行的绘制图像的函数库,想象一个小乌龟,在一个横轴为x、纵轴为y的坐标系原点,(0,0)位置开始,它根据一组函数指令的控制,在这个平面坐标系中移动,从而在它爬行的路径上绘制了图形。
1.方块圣诞树
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()

2.线条圣诞树
import turtle

def tree(d, s):
if d <= 0:
return
turtle.forward(s)
tree(d - 1, s * .8)
turtle.right(120)
tree(d - 3, s * .5)
turtle.right(120)
tree(d - 3, s * .5)
turtle.right(120)
turtle.backward(s)
n = 100
""" 设置绘图速度
'fastest' : 0
'fast' : 10
'normal' : 6
'slow' : 3
'slowest' : 1
"""
turtle.speed('fastest') # 设置速度
turtle.left(90)
turtle.forward(3 * n)
turtle.color("orange", "yellow")
turtle.left(126)
# turtle.begin_fill()
for i in range(5):
turtle.forward(n / 5)
turtle.right(144)
turtle.forward(n / 5)
turtle.left(72)
turtle.end_fill()
turtle.right(126)
turtle.color("dark green")
turtle.backward(n * 4.8)
# 执行函数
tree(15, n)
turtle.backward(n / 5)

dens = 6 #雪花瓣数设为6
snowsize = r.randint(1,10) #定义雪花大小
for j in range(dens): #就是6,那就是画5次,也就是一个雪花五角星
#t.forward(int(snowsize)) #int()取整数

t.backward(int(snowsize))
#t.bd(int(snowsize)) #注意没有bd=backward,但有fd=forward,小bug
t.right(int(360/dens)) #转动角度
drawsnow()#调用画雪花的方法
t.done() # 完成,否则会直接关闭
