Day 3: Advanced Python - Exception Handling, Web Services, and Parallel Programming

On the third day of the Python course, we'll begin by covering exception handling, a critical concept for managing errors gracefully in Python applications. Then, we'll introduce the Counter class for counting elements efficiently, and explore the datetime module for working with dates and times. The session will also include consuming web services, where participants will learn how to interact with APIs and external data sources. Finally, we'll dive into concurrency, parallelism, and multiprocessing, providing a solid understanding of how to handle multiple tasks simultaneously and improve performance in Python programs.
