前言

今天我们来画一朵玫瑰花。

一、第一种画法

这应该是最好看玫瑰花了。

二、第二种画法

第二种就稍逊一筹了，但也挺好看。

import turtle
 
# 设置初始位置
turtle.penup()
turtle.left(90)
turtle.fd(200)
turtle.pendown()
turtle.right(90)
 
# 花蕊
turtle.fillcolor("red")
turtle.begin_fill()
turtle.circle(10,180)
turtle.circle(25,110)
turtle.left(50)
turtle.circle(60,45)
turtle.circle(20,170)
turtle.right(24)
turtle.fd(30)
turtle.left(10)
turtle.circle(30,110)
turtle.fd(20)
turtle.left(40)
turtle.circle(90,70)
turtle.circle(30,150)
turtle.right(30)
turtle.fd(15)
turtle.circle(80,90)
turtle.left(15)
turtle.fd(45)
turtle.right(165)
turtle.fd(20)
turtle.left(155)
turtle.circle(150,80)
turtle.left(50)

turtle.left(20)
turtle.circle(75,105)
turtle.setheading(60)

# 花瓣2
turtle.left(180)

总结

所画玫瑰花的库用的只是turtle，但代码却很多。文章来源地址https://uudwc.com/A/R62bA
