本文主要是介绍实战 | 教你用Python画各种版本的圣诞树，希望对大家解决编程问题提供一定的参考价值，需要的开发者们随着小编来一起学习吧！

项目介绍

大家好呀，这是一份迟到的圣诞节Python专辑项目。
我们一起看看如何用Python做出超级炫酷的圣诞树吧~

1.入门版本

height = 5
stars = 1
for i in range(height):print((' ' * (height - i)) + ('*' * stars))stars += 2
print((' ' * height) + '|')

2.进阶版

import turtle
screen = turtle.Screen()
screen.setup(800,600)
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, 17):y = 30*ifor j in range(i-k):x = 30*jsquare.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 += 2if 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(17,20):y = 30*ifor j in range(3):x = 30*jsquare.goto(x,-y+280)square.stamp()square.goto(-x,-y+280)square.stamp()
turtle.exitonclick()

3.高级版本

from turtle import *
import random
import time
n = 80.0
speed("fastest")
screensize(bg='seashell')
left(90)
forward(3*n)
color("orange", "yellow")
begin_fill()
left(126)
for i in range(5):forward(n/5)right(144)forward(n/5)left(72)
end_fill()
right(126)
color("dark green")
backward(n*4.8)
def tree(d, s):if d <= 0: returnforward(s)tree(d-1, s*.8)right(120)tree(d-3, s*.5)right(120)tree(d-3, s*.5)right(120)backward(s)
tree(15, n)
backward(n/2)
for i in range(200):a = 200 - 400 * random.random()b = 10 - 20 * random.random()up()forward(b)left(90)forward(a)down()if random.randint(0, 1) == 0:color('tomato')else:color('wheat')circle(2)up()backward(a)right(90)backward(b)
time.sleep(60)
