Error Handling and Exceptions

Error handling and exceptions play a crucial role in writing robust and reliable code. They allow you to handle and recover from errors and exceptional situations that may occur during program execution. 

Types of errors and exceptions

Handling exceptions with try-except blocks

In this example, the try block attempts to perform division by zero, which raises a ZeroDivisionError. The except block catches the exception and executes the specified code to handle the error.

Handling multiple exceptions and using the else and finally blocks

In this example, the try block attempts to divide a number by 2. The except blocks handle ValueError and ZeroDivisionError if they occur. The else block is executed when no exceptions occur, and the finally block always executes, providing a cleanup mechanism.

Error handling and exceptions are essential for writing robust code that can handle unforeseen circumstances and recover from errors gracefully. By properly handling exceptions, you can improve the reliability and stability of your programs and provide better error messages and user experience.
