Noob question: why is shapesize() not working for my turtle

[adifrank]

What version of Python are you using? What platform are you running on? How do you run your program? Have you tried using turtlesize?

I'm learning through this tutorial:
https://runestone.academy/runestone/book...cises.html

It was actually recommended by someone here in this forum.

The tutorial has these little code windows where you can type your code and execute it.

That's what I'm using for now.

I just tried substituting shapesize with turtlesize, but getting same result -

AttributeError: 'Turtle' object has no attribute 'turtlesize' on line 6

I'll assume it's something buggy in the thing that is running the code in this tutorial website, unless you think it could be something else
