Python es un lenguaje de programación de alto nivel e interpretado de propósito general. A diferencia de HTML, CSS y JavaScript, que se utilizan principalmente para el desarrollo web, Python es versátil y puede emplearse en diversos campos, incluyendo el desarrollo de software, la ciencia de datos y el desarrollo back-end. En este curso, se explorarán los aspectos fundamentales de Python y, al finalizar, se podrán crear funciones propias.

Aprenda a utilizar operadores de comparación y lógicos, trabajar con expresiones condicionales y aplicar comparaciones de pertenencia y tipo. Desarrolle una base sólida en la escritura de programas que respondan dinámicamente a diferentes condiciones utilizando las estructuras if/else e if/elif/else.
