python内置库turtle绘制有趣图形

一：绘制六边形

import turtlet = turtle.Pen()turtle.bgcolor("black")sides = 6colors = ["red", "yellow", "green", "blue", "orange", "purple"]for x in range(360):    t.pencolor(colors[x % sides])    t.forward(x * 3 / sides + x)    t.left(360 / sides + 1)    t.width(x * sides / 200)

效果：

二：自定义边框

import turtlet = turtle.Pen()turtle.bgcolor("black")sides = eval(input("输入要绘制的边的数目（2-6）！"))colors = ["red", "yellow", "green", "blue", "orange", "purple"]for x in range(100):    t.pencolor(colors[x % sides])    t.forward(x * 3 / sides + x)    t.left(360 / sides + 1)    t.width(x * sides / 200)

三：带有文字的图形绘制

import turtlet = turtle.Pen()turtle.bgcolor("black")my_name = turtle.textinput("输入你的姓名", "你的名字？")colors = ["red", "yellow", "purple", "blue"]for x in range(100):    t.pencolor(colors[x % 4])    t.penup()    t.forward(x * 4)    t.pendown()    t.write(my_name, font=("Arial", int((x + 4) / 4), "bold"))    t.left(92)
