本人是Python新人小白,欢迎各位大佬指正,本文介绍的是用Python的turtle画一只小猪乔治。
还有本人画画基础超级差= =没天赋,画参考度娘上的一个图片画的。
先上总代码,然后说说我写的思路,Python学习群:683380553,有大牛答疑,有资源共享!是一个非常不错的交流基地!欢迎喜欢Python的小伙伴!
import turtle as t

t.pu() 提起画笔
t.pd() 移动时绘制图形,缺省时也为绘制
t.seth 设置当前朝向为angle角度
t.begin_fill() 准备开始填充图形
t.color 同时设置pencolor=color1, fillcolor=color2
t.goto 设置笔的坐标

说说我的代码思路。
再尝试画图之前,发现总是需要移动画笔,抬起画笔放下画笔啥的,感觉操作重复太多了,代码不好看,于是自己写了一个函数:
def move_pen(x,y):
t.pu()
t.goto(x-wight/2+50,y-height/2+50)
t.pd()
这个函数的意思就是先抬起画笔,再移动画笔,最后放下画笔准备接下来的绘制。函数里面第二行画笔移动的位置是我人为的规定了左下角是画笔的坐标原点,坐标后面加的东西类似坐标系的平移,方便后面坐标的计算。
还有一个就是设置画笔属性的函数,每次画线之前都要用这两个操作,所以我封装了下面这个函数
def pen_set(size,r1,g1,b1,r2=0,g2=0,b2=0):
t.pensize(size)
t.color((r1,g1,b1),(r2,g2,b2))
我先画了天空和草地,然后发现我画画的功底极差,没什么直觉,画一个弧线啊都要式很久,所以我自己画了一个坐标网表,这个感觉超级有用,对于确定一些细节的东西(比如眼睛嘴巴手臂尾巴什么的)的位置的调节帮助很大~建议大家画别的东西的时候也可以用一用这个方法。
def draw_grid():
pen_set(1,0,0,0,0,0,0)
for i in range(21):
move_pen(0+i*50,0)
t.seth(90)
t.fd(600)
for i in range(13):
move_pen(0,0+i*50)
t.seth(0)
t.fd(1000)
就是这样,剩下的每一个函数都是画一个身体部分的,都是手动一点一点调的参数,因为自己的画画水平不行,不知道什么时候画什么样的弧线,都是按照感觉来的,调参数的时间花了不少。
嗯,就是这么多了!
第一次写的Python代码,还有一些c的感觉在里面,没有完全转换好,有不合理的地方欢迎指出,不胜感激。
接下来就是哆啦 A 梦了~
事实上还有不少人通过 turtle 这个库实现了有趣的图,推荐去学习一下使用 turtle 这个库,其实也不难,就是需要一点耐心~
