Question

Arrange the following in correct order of exception handling in python:
(A) Write the code that may raise an exception inside a try block
(B) Execute some code regardless of whether the exception occurs or not using the finally block
(C) Handle the specific exception using the except block
(D) Raise the exception using the raise statement if necessary
Choose the correct answer from the options given below:

• A. (A), (B), (C), (D)
• B. (A), (C), (B), (D)
• C. (B), (A), (D), (C)
• D. (C), (B), (D), (A)

Answer 1

The Correct Option is B

In Python, exception handling follows a specific sequence to ensure that errors are properly managed. Here is the correct order:

1. (A) Write the code that may raise an exception inside a try block: The try block is used to wrap the code that may generate exceptions.
2. (C) Handle the specific exception using the except block: This block is responsible for catching and handling exceptions that were raised in the try block.
3. (B) Execute some code regardless of whether the exception occurs or not using the finally block: The finally block is optional and executes after the try and except blocks, allowing you to run clean-up actions such as closing files or releasing resources.
4. (D) Raise the exception using the raise statement if necessary: Although not always required, you might want to raise an exception explicitly in certain situations. This typically occurs inside a catch block or following specific conditions.

Based on these steps, the correct order from the provided options is: (A), (C), (B), (D).

Answer 2

1. Try Block (A): First, you write the code that might raise an exception inside a try block.
2. Except Block (C): Then you handle potential exceptions using one or more except blocks.
3. Finally Block (B): Optionally, you can include a finally block that executes regardless of whether an exception occurred.
4. Raise Statement (D): The raise statement can be used at any point to explicitly raise exceptions when needed.

Example Code Structure:

try:               # (A) Try block first
    # risky code
except ValueError:  # (C) Then exception handling
    # handle error
finally:           # (B) Cleanup comes next
    # cleanup code
raise Error()      # (D) Raising comes last when needed
