Exception Handling in Python
In Python, the try-except-finally statement facilitates structured exception handling with three essential components: the try block, the except block, and the finally block.
- try Block: Encloses code where exceptions may occur, anticipating potential errors.
- except Block: Follows the try block and handles exceptions that occur within it, allowing for specific actions based on exception types.
- finally Block: Optional block that follows the try and except blocks, executing code always, typically used for cleanup tasks like releasing resources.
# Function to throw ZeroDivisionError
def divide(num, den):
try:
result = num / den
except ZeroDivisionError:
print("Error: Division by zero")
else:
print("Result of division:", result)
finally:
print("End of division operation")
try:
numerator = 5
denominator = 0
divide(numerator, denominator)
except ValueError:
print("Error: Invalid input, please enter integers")
Output
Error: Division by zero End of division operation
