Why is this the easiest?

Start Coding is the easiest way to learn to program because everything is right here. You do not need to install anything or go anywhere else.  It's like having a programming book and your programming environment all in one place without having to download or install anything.  See an example after the break. What does it look like?  Well, press the "Run" button below and see:

import random import turtle r = random colors = ['red','yellow','green','blue','purple'] t = turtle.Turtle() t.speed(0) for i in range(0,10): t.down() t.fillcolor(colors[r.randint(0,len(colors)-1)]) t.begin_fill() sides = r.randint(3,9) for j in range(0,sides): t.forward(250/sides) t.left(360/sides) t.end_fill() t.up() t.goto(r.randint(-250,250),r.randint(-150,150))
