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。

from turtle import *
#设置绘制起点
setup (700,700)
#画笔颜色
pencolor("red")
hideturtle()
penup()
goto(0,280)
pendown()
left(135)
speed(0)
#左侧弧形绘制
a=0.2
for i in range (80):
    if i < 50:
        pensize(a)
        forward(2)
        a+=0.15
        if i<10:
            left(0.7)
        elif 10=50:
        pensize(a)
        forward(2.2)
        a-=0.25
        if 50=60:
        pensize(a)
        forward(2.4)
        a-=0.15
        if 60=60:
        pensize(a)
        forward(2.4)
        a-=0.16
        if 60=60:
        pensize(a)
        forward(3)
        a-=0.15
        if 60=40:
        pensize(a)
        forward(1.2)
        a-=0.15
        if 40=40:
        pensize(a)
        forward(1.2)
        a-=0.16
        if 40=50:
        pensize(a)
        forward(3)
        a-=0.15
        if 50=60:
        pensize(a)
        forward(3)
        a-=0.15
        if 50=40:
        pensize(a)
        forward(2.4)
        a-=0.15
        if 40=40:
        pensize(a)
        forward(3)
        a-=0.15
        if 40=20:
        pensize(a)
        forward(1.3)
        a-=0.15
        if 20=40:
        pensize(a)
        forward(2.5)
        a-=0.15
        if 40=40:
        pensize(a)
        forward(3)
        a-=0.15
        if 40=30:
        pensize(a)
        forward(2.5)
        a-=0.15
        if 30=40:
        pensize(a)
        forward(2.5)
        a-=0.15
        if 40=60:
        pensize(a)
        forward(3.5)
        a-=0.08
setheading(0)
penup()
goto(-16,-70)
pendown()
right(91)
a=1
for i in range (120):
    if i < 60:
        pensize(a)
        forward(3.5)
        a+=0.08
    elif i >=60:
        pensize(a)
        forward(3.5)
        a-=0.08
setheading(0)

speed(1)
penup()
goto(-16,-150)
pendown()
pensize(3)
left(35)
forward(15)
setheading(0)
right(115)
forward(34)

setheading(180)
penup()
goto(-49,-250)
pendown()
pensize(3)
right(35)
forward(15)
setheading(180)
left(115)
forward(34)
input()
done

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.circle(150,90)
turtle.end_fill()
 
# 花瓣1
turtle.left(150)
turtle.circle(-90,70)
turtle.left(20)
turtle.circle(75,105)
turtle.setheading(60)
turtle.circle(80,98)
turtle.circle(-90,40)
 
# 花瓣2
turtle.left(180)
turtle.circle(90,40)
turtle.circle(-80,98)
turtle.setheading(-83)
 
# 叶子1
turtle.fd(30)
turtle.left(90)
turtle.fd(25)
turtle.left(45)
turtle.fillcolor("green")
turtle.begin_fill()
turtle.circle(-80,90)
turtle.right(90)
turtle.circle(-80,90)
turtle.end_fill()
 
turtle.right(135)
turtle.fd(60)
turtle.left(180)
turtle.fd(85)
turtle.left(90)
turtle.fd(80)
 
# 叶子2
turtle.right(90)
turtle.right(45)
turtle.fillcolor("green")
turtle.begin_fill()
turtle.circle(80,90)
turtle.left(90)
turtle.circle(80,90)
turtle.end_fill()
 
turtle.left(135)
turtle.fd(60)
turtle.left(180)
turtle.fd(60)
turtle.right(90)
turtle.circle(200,60)

总结

所画玫瑰花的库用的只是turtle，但代码却很多。
