Use exception handling to deal with errors gracefully from "summary" of Python For Dummies by Stef Maruch,Aahz Maruch
Exception handling is a crucial aspect of programming that allows you to anticipate and deal with errors that may occur during the execution of your code. By using exception handling, you can ensure that your program continues to run smoothly even if unexpected errors occur. When an error occurs in a Python program, an exception is raised. If this exception is not handled properly, the program will terminate abruptly, potentially leaving the user confused or frustrated. By using try and except blocks, you can catch exceptions and handle them gracefully. The try block contains the code that may raise an exception, while the except block specifies how to handle the exception if it is raised. You can also use multiple except blocks to handle different types of exceptions separately. This allows you to provide specific error messages or take different actions depending on the type of error that occurred. Additionally, you can use the else block to execute code only if no exceptions were raised in the try block. This can be useful for performing cleanup actions or displaying a success message. Finally, you can use the finally block to execute code that should always run, regardless of whether an exception was raised. This can be helpful for releasing resources or closing files, ensuring that your program maintains good housekeeping practices. By using exception handling effectively, you can make your code more robust and user-friendly, ensuring that errors are handled gracefully and your program continues to run smoothly under various circumstances.
