Learning with Turtle Art

Play with Turtle Art to draw colorful art patterns using a turtle that accepts instructions for movement.

With visual programming blocks, you can snap together programs by compiling (combining) them in ways to create anything you can imagine.

  Calculating the hypotenuse and approximating the angle of a right triangle
• 
  Stepping through the program is a nice way to visualize the process of approximation
• 
  The final result of the approximation.

  And on-the-fly function definitions

Tony Forster describes his "adventures" with on-the-fly definitions to create an analog clock in his blog.

Try any of the time or math library functions, e.g.,

localtime().tm_min 

sin(x) + sin(pi/2)

sensors

Turtle Art supports sensor input:

  Q: How do I cast keyboard input to a string? Looking at the source your are using ord() to fetch the input... is there a way to convert that back to string before showing it? ANS: Use chr(). See the example in the illustration.
