The ________ block handles an exception.

The block that handles an exception in programming is known as the "try-except" block.

Exceptions are events that occur during the execution of a program that disrupt its normal flow. They may occur due to errors in the code or unexpected conditions like invalid input, unavailable resources, etc.

The "try" block is used to wrap the code segment that might produce an exception. If that code generates an exception, it will be caught and handled by the subsequent "except" block.

The "except" block follows the "try" block and is used to catch and handle the exception raised in the "try" block. It can specify the type of exception it handles, or catch a generic exception if no specific type is mentioned.

Consider an example to calculate the division of two input numbers: 1. Wrap the code that may raise an exception in a "try" block. ``` try: num1 = int(input("Enter the first number: ")) num2 = int(input("Enter the second number: ")) result = num1 / num2 ``` 2. Add the "except" block to handle the exception, in this case, a "ZeroDivisionError" for division by zero, and a "ValueError" for invalid input. ``` except ZeroDivisionError: print("Error: Division by zero is not allowed.") except ValueError: print("Error: Invalid input. Please enter a valid number.") ``` 3. If the "try" block runs without raising an exception, the result is printed outside the "try-except" block. ``` else: print("The result of the division is: ", result) ``` 4. The complete code for the example: ``` try: num1 = int(input("Enter the first number: ")) num2 = int(input("Enter the second number: ")) result = num1 / num2 except ZeroDivisionError: print("Error: Division by zero is not allowed.") except ValueError: print("Error: Invalid input. Please enter a valid number.") else: print("The result of the division is: ", result) ```
