Python 3: Handling Errors -

: Pythonic code often follows "Easier to Ask Forgiveness than Permission" (EAFP)—trying an operation and handling the failure rather than checking if it's possible beforehand. Common Built-in Exceptions

: Always runs regardless of whether an error occurred. This is essential for resource cleanup , such as closing files or database connections. Strategic Techniques Python 3: Handling errors

: Contains the code that executes if a specific error occurs. : Pythonic code often follows "Easier to Ask

For more complex logic, Python provides two optional clauses: Strategic Techniques : Contains the code that executes

In Python 3, error handling is managed through , which are events that disrupt the normal flow of a program . Mastering these tools allows you to create robust applications that can recover from issues like invalid user input or missing files instead of crashing. The Core Mechanism: try...except

: Avoid using a bare except: or except Exception: . Catching specific errors (e.g., FileNotFoundError ) prevents you from accidentally silencing unexpected bugs you didn't intend to handle.
