# Interactive Drawing
# Shapes
# This is an overview of the shapes that can be drawn on the
#canvas. For full details, please look at the documentation.
#If you are having issues figuring out which shape is drawn
#by which line of code, try commenting some of them out.
# General notes: It is acceptable to use either () or [] when
#listing points. However, be careful that you match
#the number and type of () or [] that you are using. Also,
#polygons and circles have optional parameters that allow
#you to select a fill color.

This Should Work :)
