turtle—‘小小爱心火柴人’

这两天在学习Python的turtle，昨天下午用 goto() 语句画了一个火柴人，今天改进了一下，并加了两个爱心。
#改进前代码

from turtle import *
#color("red", "yellow")
bgcolor('azure')
pensize(10)
pencolor("yellow")
goto(0,100)
color("yellow","pink")
begin_fill()
circle(30)
end_fill()
goto(0,0)
goto(-70.7,-70.7)
goto(0,0)
goto(70.7,-70.7)
goto(0,0)
goto(0,50)
goto(42.5,75)
pencolor("pink")
goto(42.5,90)
goto(42.5,75)
pencolor("yellow")
goto(0,50)
goto(-42.5,25)
pencolor("pink")
goto(-42.5,10)
hideturtle()
done()

运行效果

七夕节，想着写一个什么复习一下前几天学的东西，看文章有一个漫天星的想法很不错，并且也切合这个主题，于是就写了一个漫天心的代码

'''七夕，满天心'''
import turtle as t
import random

t.bgcolor('azure')  #画板颜色，浅蓝


def go_to(x, y):
    t.up()
    t.goto(x, y)
    t.down()


#画心
def draw_heart(size, color_):
    #color('red', color_)
    t.speed(0)
    t.colormode(255)
    t.color(color_)
    t.begin_fill()
    #t.left(120)  效果不同
    t.setheading(120)  #爱心正
    t.forward(30 * size)
    t.circle(-8.66*size, 180)
    t.left(120)
    t.circle(-8.66*size, 180)
    t.forward(30 * size)
    t.end_fill()


#漫天心
def draw_pic():
    # color  三原色
    colors_1 = random.randint(0, 255)
    colors_2 = random.randint(0, 255)
    colors_3 = random.randint(0, 255)
    t.penup()
    # pos
    x = random.randint(-400, 400)
    y = random.randint(-200, 200)
    go_to(x, y)
    # size
    size = random.randint(0, 4)
    draw_heart(size, (colors_1, colors_2, colors_3))


def main():
    t.hideturtle()
    t.setup(900, 700) #画屏大小
    # number
    for i in range(20):
        draw_pic()
    go_to(-100, 0)
    t.pencolor('red')
    t.write("七夕，在一起！", move=True, align="left", font=("华文行楷", 20, "normal"))
    go_to(-445, 315)
    t.write("To:My dear！", move=True, align="left", font=("Comic Sans MS", 20, "normal"))
    t.done()


main()
