I have a project for which I need to use turtle. I'm very new to python, and our teacher didn't really explain how to use turtle. What's the basic format I need to use to draw a polygon? I have to define a function, polygon(), and run it with two parameters as: polygon(sides, length). Do I import turtle first? Do I use for loops? I don't need someone to do the project for me; I just have absolutely no idea how turtle works and where to start. HELP please!!!!
