1.画圣诞树

import turtle
screen = turtle.Screen()
screen.setup(800,600)
circle = turtle.Turtle()
circle.shape('circle')
circle.color('red')
circle.speed('fastest')
circle.up()

square.color('green')
square.speed('fastest')
square.up()
circle.goto(0,280)
circle.stamp()
k = 0
for i in range(1, 17):
    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:

​
    turtle.showturtle()     # 显示画笔
​
# 初始化
​
turtle.setup(width=800, height=500)     # 窗口（画布）大小
​
turtle.color('red', 'pink')     # 画笔颜色
​
turtle.pensize(2)       # 画笔粗细
​
turtle.speed(0.5)     # 描绘速度
​
# 初始化画笔起始坐标
​
move_pen_position(x=0,y=-180)   # 移动画笔位置
​
turtle.left(140)    # 向左旋转140度
​
turtle.begin_fill()     # 标记背景填充位置
​
# 画心形直线（ 左下方 ）
​
turtle.forward(224)    # 向前移动画笔，长度为224
​
# 画爱心圆弧
​
hart_arc()      # 左侧圆弧
​
turtle.left(120)    # 调整画笔角度
​
hart_arc()      # 右侧圆弧
​
# 画心形直线（ 右下方 ）
​
turtle.forward(224)
​
turtle.end_fill()       # 标记背景填充结束位置
  
# 点击窗口关闭程序
​
window = turtle.Screen()
​
window.exitonclick()

5.画玫瑰花

6.画太极

#引入turtle函数库

​
#定义画半个太极图的函数，第一个参数radius是大圆的半径，
​
#color1，color2分别是两种填充颜色，对应图形中的黑白填充
​
def draw(radius, color1,color2):

    #设置画笔粗细
    width(3)
​
    #设置画笔颜色和填充颜色
    color("black",color1)

    #准备开始填充图形
    begin_fill()
​
    #首先画一个半径为radius/2，弧度为180的半圆，画的是红线所示半圆
    circle(radius/2,180)
​
    #画一个半径为radius，弧度为180的半圆，画的是黄线所示半圆
    circle(radius,180)
​
    #将画笔方向旋转180度
    left(180)
​
    #画一个半径为radius/2，弧度为180的半圆，此时半径值为负，
​
    #圆心在画笔的右边，画的是绿线所示半圆
    circle(-radius/2,180)
​
    #结束填充
    end_fill()
​
    #画笔向左旋转90度，正好指向画板上方
​
    left(90)
​
    #抬起画笔，再运动时不会留下痕迹
    up()
​
    #向前移动radius*0.35，这样小圆边线距离大圆边线上下各radius*0.35，
​
    #小圆的半径就为radius*0.15
    forward(radius*0.35)
​
    #画笔向右旋转90度，指向画板右侧
    right(90)
​
    #放下画笔
    down()
​
    color(color2,color2)
​
    #开始画内嵌小圆，如蓝线所示
    begin_fill()
​
    circle(radius*0.15)
​
    end_fill()
​
    #旋转画笔90度，指向画板上方
    left(90)
​
    up()
​
    #后退radius*0.35
    backward(radius*0.35)
​
    down()
​
    #旋转画笔90度，指向画板左方
    left(90)
​
#定义主函数
def main():
​
    #设置窗口或者画板大小
    setup(500,500)
​
    #绘制黑色一半，白色内圆
    draw(200,"black","white")
​
    #绘制白色一半，黑色内圆
    draw(200,"white","black")
​
    #隐藏画笔
    ht()
​
main()
