python圣诞树代码
1、简单的绘制圣诞树
新建tree1.py或者直接输⼊下⾯代码运⾏#声明树的⾼度
height = 5
#树的雪花数，初始为1
stars = 1
#以数的⾼度作为循环次数
php工程师学徒招聘for i in range(height):
print((' ' * (height - i)) + ('*' * stars))
stars += 2
#输出树⼲
print((' ' * height) + '|')
2、使⽤turtle绘制简单圣诞树
新建tree2py，输⼊以下代码#导⼊turtle库import turtle
#设置屏幕⼤⼩
screen = turtle.Screen()
screen.setup(800,600)
#获取画笔并设置⼀些属性：圆形、红⾊、快circle = turtle.Turtle()
circle.shape('circle')
circle.speed('fastest')
#抬起画笔
circle.up()
#重新获取画笔
square = turtle.Turtle()

#重新设置画笔属性：四⽅形、绿⾊、快square.shape('square')
square.speed('fastest')
#重新抬起画笔
square.up()
#跳到指定坐标位置
<(0,280)
#复制当前图形
circle.stamp()
k = 0
for i in range(1, 17):
y = 30*i
for j in range(i-k):
x = 30*j
<(x,-y+280)
square.stamp()
<(-x,-y+280)
square.stamp()
excel trim
if i % 4 == 0:
x = 30*(j+1)
<(x,-y+280) circle.stamp()
k += 2
if i % 4 == 3:
x = 30*(j+1)
<(x,-y+280) circle.stamp()
y = 30*i
for j in range(3):
x = 30*j
<(x,-y+280) square.stamp() (-x,-y+280) square.stamp()

3、使⽤Turtle绘制复杂圣诞树
新建tree3.py，输⼊以下代码#导⼊所依赖的库from turtle import *
import random
import time
n = 80.0
#设置速度快
speed("fastest")
#背景颜⾊ 海贝壳⾊，偏粉⾊
screensize(bg='seashell')

if random.randint(0, 1) == 0: color('tomato')
else:
color('wheat')
circle(2)
up()
