I need some help with this question relating to TurtleGraphics in Python: A small detail of tipsy_turtle() is that when the turtle turns 90 degrees it immediately "jumps" to the new direction.

locals is a built in function that returns a dictionary of local values. The documentation says: Warning The contents of this dictionary should not be modified; changes may not affect the values of local variables used by the interpreter.

I believe...
