It probably raises an exception and prints a traceback. That "traceback"
contains the location and a description of the error Python encountered in
your script and is therefore valuable information that can help you fix your
code. If you get a traceback always include it into your mail (use cut-and-
paste).

That's pretty unreadable. Please remember to post plain text with line-
wrapping turned off next time.

If I were to guess: Did you define the `free_squares` list of lists
properly?

Are you running your script from within IDLE? Try starting it from the
command line instead.
Like turtle IDLE itself is a program written in tkinter, and the separation
between editer and user code is not always perfect.
