4. El Capítulo Estrella: Gráficos con graphics.py

Un punto donde este libro brilla con luz propia es en su enfoque visual. Muchos libros de texto basan sus ejemplos en cálculos matemáticos aburridos o texto en consola. Zelle desarrolló una librería propia llamada graphics.py, basada en la biblioteca estándar Tkinter.
