This follows on from CoderDojo turtle racing – 1 – oval track. Copy your Python code from the first post and run it in this one. This time you will get a score showing how long it took your turtle to get around the track.

# Turtle racing track = oval track with score
# Don't edit the lines for turtle "track"
# Edit the lines for turtle "racer"
# between "# ninja start" and "# ninja end"
# See if you can find the fastest way around the track
# Make sure the turtle doesn't touch the sides

import turtle

# turtle which draws track
track = turtle.Turtle()
track.speed(0)
track.color("black")
track.penup()

# inside of track

track.pendown()
track.forward(100)
