Handling Code After Exceptions

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


              1234567
            
try:
    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


              123456789
            
try:
    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.
