ejemplo en python
No me esforcé mucho en aplicar TDD. De hecho apliqué el método Obvious Implementation a full. A si que cabe aclarar que no le dediqué mucho tiempo al ejercicio, pero haré igual la PR por si a alguien le sirve el ejemplo en python Pero sí el ejercicio me sirvió para empezar, de partida a generar el setup para un proyecto con test en python y tambien a hacer mis primeros test en Python :raising_hands: Muchas gracias.
