Python學習之turtle繪圖篇

畫一個紅色的五角星

from turtle import *
color('red','red')
begin_fill()
for i in range(5):
    fd(200)
    rt(144)

end_fill()
done()

效果圖：

畫一條蟒蛇

#PythonDraw.py
import turtle
#turtle.setup(650,350,200,200)
turtle.penup()
turtle.fd(-250)
turtle.pendown()
turtle.pensize(25)
turtle.pencolor("purple")
turtle.seth(-40)
for i in range(4):
    turtle.circle(40,80)
    turtle.circle(-40,80)
turtle.circle(40,80/2)
turtle.fd(40)
turtle.circle(16,180)
turtle.fd(40*2/3)

效果圖：

畫一組內切圓

import turtle
turtle.pensize(2)
turtle.circle(10)
turtle.circle(40)
turtle.circle(80)
turtle.circle(120)

效果圖：

畫一個社會人小豬佩奇，代碼是借鑒某位大佬的

簡單總結一下好了，其實turtle庫還是非常有用的，以后可以畫張很有創意的圖片去表白女神了，講不好那天就用上了呢：

顯示器和turtle窗體的左上角都是原點
turtle.setup(width,height,startx,starty)設置窗體大小及位置，后面兩個參數可選，非必需
空間坐標：絕對坐標：右方向x軸，上方向為y軸，正中心為原點，turtle.goto(x,y)讓在任何位置的海龜到達指定的位置
海龜坐標：turtle.fd(d)海龜向前行多少像素
turtle.bk(d)向海龜的反方向運行
turtle.circle(r,angle)以海龜左邊的某一點為圓心進行曲線運行
角度坐標：絕對角度：turtle.seth(angle)angle為絕對度數，表示改變海龜的運行方向
海龜角度：turtle.right(angle),turtle.left(angle)改變海龜的運行方向
RGB體系：turtle.colormode(mode)mode=1.0則改用0和1表示，mode=255則改用255和0表示，默認為小數
庫引用：import <庫名>,from <庫名> import *或者from <庫名> import <函數名>,import <庫名> as <庫別名>
畫筆控制函數：turtle.penup()別名：turtle.pu()抬起畫筆，turtle.pendown()別名：turtle.pd()落下畫筆，turtle.pensize(width)別名：turtle.width(width)設置畫筆寬度，turtle.pencolor(color)設置畫筆顏色，color有三種方式，顏色字符串，或者RGB小數值，或者RGB元組值，例如：turtle.pencolor((0.63,0.13,0.94))
運動控制函數:turtle.circle(r,angle),r（海龜左方向）表示半徑，angle表示繪制的角度，默認是360度
方向控制函數：turtle.seth(angle)改變海龜的行進方向，順時針轉向
