这学期选修课选的趣味python，和丁哥一起上选修课简直太开心了，每次下课我都不愿意走，因为老是能向丁哥学到好多好玩的，我们俩老是不听老师讲课自己在下面玩自己的，可是我知道这样是不对的，老师讲的主要是用python画图，讲的比较简单，我就记了一些笔记，也把我学来的那些好玩的分享一下，欢迎大家去访问丁哥的博客~：https://blog.csdn.net/ydydyd00 里面有太多好玩的啦~

turtle 函数

turtle.penup()

turtle.pendown()

turtle.pensize()画笔粗细

turtle.fd()向前走

turtle.left()向左转

turtle.right()向右转

turtle.speed(0) 为零时画笔速度最快

turtle.setup(width,height,startx,starty)，启动一个图形窗口，设置窗口位置，

turtle.circle(半径，角度）

range(n) 产生0到n-1的整数序列，共n个

例如：range（5）即 0，1，2，3，4

range（m，n）生成一个[m，n )的序列

例如：range（3，9）即 3，4，5，6，7，8

range(m,n,k) 生成一个[m,n)之间以k为步长的随机整数

例如：range（1，9，2）即 1，3，5，7

s = s[:-x] 切片；（为x=1去掉最后一个字符）

画笔定位函数调用：

def setpen(x,y):

t.penup()

t.goto(x,y) //移动到以起始点为原点在坐标系中的（x,y)

t.pendown()

t.setheading(0) //笔尖旋转角度

setpen(-200,0) //使起始点向x负方向移动200px

第一堂课实战内容：

import turtle

t = turtle.Turtle()

t.speed(0)

for i in range(500):

t.forward(i)

t.right(91)

turtle.done()

import turtle

def colorstar(c1,c2,d):

p.color(c1,c2)

p.begin_fill()

for i in range(5):

p.forward(d)

p.right(144)

p.end_fill()

Icolor = input("input a line color")

Fcolor = input("input a fill color")

length = eval(input("input the length of line"))

colorstar(Icolor,Fcolor,length)

turtle.done()

画小青蛇：

import turtle

def drawSnake(rad,angle,len,neckrad):

for i in range(len):

turtle.circle(rad,angle)

turtle.circle(-rad,angle)

turtle.circle(rad,angle/2)

turtle.forward(rad/2)

turtle.circle(neckrad,180)

turtle.forward(rad/4)

if __name__ == "__main__":

turtle.setup(1500,1400,0,0)

turtle.pensize(30)

turtle.pencolor("green")

turtle.seth(-40)

drawSnake(70,80,2,15)

turtle.done()

画机器猫：

for i in range(120):

if 0 <= i < 30 or 60 <= i < 90:

else:

a += 0.05
