I am new to python and have a question about using methods.
Here is the link i am looking at:
http://www.pythonware.com/library/tkinter/introduction/x2102-methods.htm
If i use, create_arc(bbox, options) => id
what is id? and how do i find the parameter list representing options?
Search for create_arc, and you'll find
http://www.pythonware.com/library/tkinter/introduction/x2861-options.htm
as one of the links. The link "Back" will get you to:
http://www.pythonware.com/library/tkinter/introduction/canvas-arc.htm
which is the beginning of Chapter 14, "The Canvas Arc Item"
As for 'id' I have no idea, but if you read further, you'll probably
find out. The fact that all of these methods return one indicates it's
some sort of object reference for those widgets.
Everything drawn on a canvas has an 'id' which just happens to be an
integer (treat it as a magic cookie). You specify that id to the
canvas to talk about that particular element, but you often group
canvas elements together via "tags", and use the same canvas operations
on a tag so that you can do your operation to everything with that tag.
operations include such things as color manipulation, delete, clone,
and move.
