Python es un lenguaje de programación de alto nivel, interpretado y de propósito general. A diferencia de lenguajes como HTML, CSS y JavaScript, que se utilizan principalmente en el desarrollo web, Python destaca por su versatilidad en múltiples dominios, incluyendo el desarrollo de software, la ciencia de datos y el desarrollo back-end. Este curso te guiará a través de los conceptos fundamentales de Python, proporcionándote las habilidades necesarias para crear tus propias funciones al finalizar el programa.

En esta sección, se explorarán los fundamentos de Python, se familiarizará con el entorno de trabajo, se realizarán operaciones matemáticas simples y se mostrarán los resultados.
