Python è un linguaggio di programmazione di alto livello, interpretato e di uso generale. A differenza di HTML, CSS e JavaScript, utilizzati principalmente per lo sviluppo web, Python è versatile e può essere impiegato in diversi ambiti, tra cui lo sviluppo software, la data science e lo sviluppo back-end. In questo corso verranno esplorati gli aspetti fondamentali di Python e, al termine, sarai in grado di creare le tue funzioni.

Approfondimento delle basi di Python, esplorazione dell'ambiente di lavoro ed esecuzione di semplici operazioni matematiche. Apprendimento delle modalità per scrivere codice leggibile utilizzando i commenti e gestione di espressioni matematiche sia di base che avanzate con visualizzazione dei risultati.
