Letter to Ole about a new turtle.py is not meaningful, because the version uses uses tkinter NOT available on an iphone. Read about it just 11.6.2921.

For other systems it seams to be much more in speed with two nice examples included..
Have a nice day
Peter ( or PKHG ...)

Problem solved, new phone has below left either abc or 123 button and that is start first too other 123 cides shows a lot of other signs
