It's been a while since I used Tkinter, but from memory: To get the mouse coordinates, you'll need to use events. Check out http://effbot.org/tkinterbook/tkinter-events-and-bindings.htm for some details. Essentially, you'll need to bind a function to the B1-Motion event, and then inspect the event object to find out the mouse location. (I'm assuming here that you only want to draw your lines when the user has a button depressed..) To draw points, you could perhaps use canvas.create_oval with a small bounding box.
