File Handling

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).

Solution: The task involves matching function calls related to file seeking with their respective descriptions. In Python, the seek() method is used with a file object to change the file's current position. The method signature is f.seek(offset, whence) where offset is the number of bytes to move and whence determines the reference position.

• whence=0: Move the pointer from the beginning of the file. This is the default. (e.g., f.seek(10))
• whence=1: Move the pointer from the current file position. (e.g., f.seek(10,1) or f.seek(-10,1))
• whence=2: Move the pointer from the end of the file. (e.g., f.seek(-10,2))

Now, match the statements to their meanings:

Therefore, the correct match is: (A) - (II), (B) - (III), (C) - (I), (D) - (IV)
