Exception handling in python

exception handling in python allows you to handle and manage errors that might occur during the execution of your code. by using try and except blocks, you can catch and handle exceptions gracefully, preventing your program from crashing.
here's a breakdown of how exception handling works in python:
1. **try block**: in a try block, you place the code that you want to run and monitor for exceptions. if an exception occurs in this block, python will jump to the corresponding except block.
2. **except block**: in an except block, you can define the type of exceptions you want to catch and then specify the actions to be taken when that exception occurs. if an exception matches the type specified in the except block, the code inside the except block will be executed.
3. **finally block**: you can also include a finally block after the try-except block. code within the finally block will always be executed, regardless of whether an exception occurred or not. this block is commonly used for cleanup actions.
here's an example code snippet demonstrating exception handling in python:
in the first part of the code, a zerodivisionerror is caught when dividing by zero, and an appropriate error message is printed. in the second part, a valueerror is caught when the user enters a non-numeric input.
exception handling is essential in writing robust and reliable code. it allows you to handle errors gracefully and take appropriate actions to maintain the stability of your program.
