Apr 2, 2025 · Exception handling in Python is done using the try, except, else and finally blocks. try Block: try block lets us test a block of code for errors. Python will “try” to execute the code in this block. If an exception occurs, execution will immediately jump to the except block. except Block: except block enables us to handle the error or exception.

When an error occurs, or exception as we call it, Python will normally stop and generate an error message. These exceptions can be handled using the try statement: The try block will generate an exception, because x is not defined: Since the try …

The try...except block is used to handle exceptions in Python. Here's the syntax of try...except block: try: # code that may cause exception except: # code to run when exception occurs

Jan 12, 2025 · Error handling is a way to anticipate, detect, and resolve exceptions without crashing your program. Python achieves this using try-except blocks, which allow you to: Catch exceptions and handle them gracefully. Execute alternative code when an error occurs. Prevent the program from terminating abruptly.

Python exception handling lets you catch and manage errors, preventing program crashes. Instead of stopping execution when an error occurs, Python gives you tools to handle issues gracefully and keep your code running smoothly. You can use the try-except block to catch exceptions and execute alternative code. The basic syntax looks like this:
