13.1. Exception Handling

In this section, we explore exceptions in Python, which are errors that occur during program execution, even when the syntax is correct. Exceptions like ZeroDivisionError or ValueError provide information about what caused the error, and they help developers understand issues in their programs.

Exception handling allows programs to continue running even when certain errors occur. This is done using try and except blocks.

The try block contains the code that might raise an exception, while the except block specifies what to do if an exception occurs.

For example, when a user provides invalid input that triggers a ValueError, the program can handle it without crashing. By anticipating and managing exceptions, developers can make their programs more robust and user-friendly.
