import error while importing turtle

I am a student and need to work on a project using turtle. I get an importing error when trying to import turtle. I am on Mac OS High Sierra. Following is the code and error:

import turtle
screen = turtle.Screen()
screen.setup(width=800, height=600)
turtle1 = turtle.Turtle()
screen.exitonclick()

Traceback (most recent call last):
