用python画圣诞树的代码

如何用python画一个圣诞树呢？

一、最简单的绘制圣诞树

代码也特别简单：

# 最简单的绘制圣诞树

height = 5                        # 树的高度
stars = 1                         # 树的雪花数，初始为1
for i in range(height):            # 以树的高度作为循坏次数
    print(( * (height - i)) + (* * stars))
    stars += 2
    print((*height)+|)         # 输出树干

运行结果：

二、使用turtle绘制简单圣诞树

# 导入turtle库
import turtle

# 设置屏幕大小
screen = turtle.Screen()
screen.setup(375, 700)

# 获取画笔并设置一些属性：圆形、红色、快
circle = turtle.Turtle()
circle.shape(circle)
circle.color(red)
circle.speed(fastest)
circle.up()            # 拾起画笔

# 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.color(green)
square.speed(fastest)
square.up()          # 重新拾起画笔

# 跳到指定坐标位置
circle.goto(0, 280)
circle.stamp()       # 复制当前图形

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()

运行结果：

三、使用Turtle绘制复杂圣诞树

import turtle

# 定义圣诞树的绿叶函数
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)

运行结果：

本是动态效果，运行出来的结果就是这样，大家感兴趣的话可以自己试一试

祝大家圣诞节快乐哦！！！
