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
改进后的代码

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()
