Triangle Function
Back to index
This sample program just produces a bunch of triangles, but each time the
program is run the triangles wind up in different spots. Get this sample up
and running and be sure to test it out by running it several times.

The use of the randint function and the following user defined function are
the most interesting features of this sample program.

canvas.create_line(x,y,x-s/2,y+s,fill="magenta", width=3);

The height and the base of these triangles is the same. Therefore, what type
of triangle are they?
ASSIGNMENT:
Your assignment will be to create a 12x12 array of randomly colored
triangles of uniform size. So, the size and arrangement of the triangles will
always be the same, but the color distribution will change each time the
program runs. Use at least six different colors.
