Executing Code After Exceptions: Handling Cleanup Operations
The try, except, else, and finally clauses form a combination that handles exceptions, performs cleanup, and executes code based on whether exceptions were raised or not.
When No Exceptions Raised
The else block is executed if NO exceptions were raised in the try block. It is useful for code that must be executed if the try block did not throw an error but should not be executed if there was an error.
Example Usage
1234567try: print("Trying to divide") result = 10 / 2 except ZeroDivisionError: print("Divided by zero!") else: print("Division successful:", result)
In this example, the else clause runs only if no ZeroDivisionError is caught in the try block.
Executing Cleanup Actions
The finally block lets you execute code, regardless of whether an exception was raised or not. This is typically used for clean-up actions.
Example Usage
123456789try: print("Trying to divide") result = 10 / 0 except ZeroDivisionError: print("Divided by zero!") else: print("Division successful:", result) finally: print("Operation attempted.")
In this scenario, the finally clause will execute regardless of whether the try block succeeds or the except block catches an exception, ensuring that the message "Operation attempted." is printed in every case.
Swipe to start coding
Implement a complete error handling block with try, except, else, and finally clauses. Your task is to handle a simple calculation process.
