My point is, you should look for a higher-level of interface than
single pixels. What do you want to plot? Bitmap images? Graphs and
charts? Sprites?

Pygame and Pyglets and PIL will help to create and draw bitmaps and sprites.
PyOpenGL is perhaps the closest to the hardware.
matplotlib and a host of others are good for graphs and charts.
There are several good 3-D rendering programs for python
Tkinter Canvas lets you draw basic shapes
