hello大家好，今天教大家话五彩正方形先看代码

import turtle


mypen = turtle.Pen()

mypen.speed(0)
mypen.pensize(3)
colors = ['rad', 'orange', 'yellow', 'green', 'blue', 'indigo', 'purple']
for i in range(4):
    for j in range(7):
        mypen.pencolor(colors[j])
        mypen.forward(20)
    mypen.left(90)

mypen = turtle.Pen()【先设置一个画笔mypen】

mypen.speed(0)【画笔速度为0.这里数字越小速度越快】
mypen.pensize(3)【画笔粗细为3.这里数字越大越粗】
colors = ['rad', 'orange', 'yellow', 'green', 'blue', 'indigo', 'purple']【设置一个变量存入7个颜色】
for i in range(4):【重复执行4次】
    for j in range(7):【二次循环重复7次】
        mypen.pencolor(colors[j])【每次换一个颜色】
        mypen.forward(20)【向前走二十步】
    mypen.left(90)【向左转90度】

结果
