* gh-118673: Remove shebang and executable bits from stdlib modules. * Removed shebangs and exe bits on turtledemo scripts. The setting was inappropriate for '__main__' and inconsistent across the other modules. The scripts can still be executed directly by invoking with the desired interpreter.

A simple event-driven paint program
|
|
|
|
- left mouse button moves turtle
|
|
- middle mouse button changes color
|
|
- right mouse button toggles between pen up
|
|
(no line drawn when the turtle moves) and
|
|
pen down (line is drawn). If pen up follows
|
|
at least two pen-down moves, the polygon that
|
|
includes the starting point is filled.
|
|
-------------------------------------------
|
|
Play around by clicking into the canvas
|
|
using all three mouse buttons.
|
|
-------------------------------------------
|
|
To exit press STOP button
