Python—turtle库画图神器

引入turtle库画图简直无敌，之前用过MATLAB的plot函数，感觉这个更强大，有海量的第三方库，简直完美有趣

1.彩色螺旋线的绘制

import turtle import time turtle.pensize(2) turtle.bgcolor("black") colors = ["red", "yellow",'purple','blue'] turtle.tracer(False) for x in range(400):  turtle.forward(2*x)  turtle.color(colors[x % 4])  turtle.left(91) turtle.tracer(True)

2.太阳花的绘制

from turtle import * color('red', 'yellow') begin_fill() while True:forward(200) left(170) if abs(pos()) < 1:break end_fill() done()

3.五角星的绘制

from turtle import * fillcolor("red") begin_fill() while True:forward(200)     right(144)    if abs(pos()) < 1:    break end_fill()

4.螺旋线绘制

import turtle import time turtle.speed("fastest") turtle.pensize(2) for x in range(100):turtle.forward(2*x)turtle.left(90) time.sleep(3)
