Even the best-written programs can run into problems — like asking the user to enter a number, but they type in a word instead. If your code isn’t ready for that, it can crash. That’s where error handling comes in. In Python, we use try and except blocks to catch and deal with errors, so your program can keep running smoothly even when something goes wrong.
In this section, you’ll learn how to wrap risky code in a try block and provide a backup plan in the except block. This is useful for preventing crashes when working with user input, files, or any situation where unexpected data might appear. By learning to catch and manage errors, you’ll make your programs more reliable and professional.
