Python uses which constructs to handle errors during execution?

Python uses exception-handling constructs to manage errors that may arise during the execution of a program. This mechanism allows developers to gracefully respond to errors, rather than allowing the program to crash or behave unpredictably.

When an error occurs in Python, an exception is raised, and the interpreter searches for a corresponding exception handler. This is typically done using the try and except blocks. Within the try block, you can place code that might potentially raise an exception. If an exception is raised, the flow of control shifts to the except block, where you can handle the error appropriately. This can include logging the error, cleaning up resources, notifying the user, or taking any other corrective actions.

By using exception-handling, Python provides a robust way to manage runtime errors, ensuring that applications can maintain stability and provide meaningful feedback even in the face of unexpected situations. This contrasts with other constructs like control flow or conditionals, which are not specifically designed for error management.
