I recently discovered the turtle module and have been playing around with it for the last few days. I've started writing some functions for turtles, and would like to make them a bit more robustly than what I currently have.
In particular, I'd like the state of the turtle to be more or less the same after the function return as it was before the function invocation. In order to turn the turtle, I need to select a way to represent angles. I could use either degrees or radians (or, I suppose, grads). However, for my functions to work, I need to set the turtle to that mode. This means that I could possibly mess up things for the caller. What I would like to do is capture the angle-representation mode on entry and restore it on return. However, looking through the methods of turtle.Turtle(), I can't find any means of capturing this information. Similarly, I'd like to return with the pen in the same state (up or down) as when my functions were called. Again, I can't find any way to query the pen state. How can my function get this information? Or do I need to be sloppy and let the callers beware? -- Michael F. Stemper 2 Chronicles 19:7 -- https://mail.python.org/mailman/listinfo/python-list
