Question

Match List-I with List-II:

List-I	List-II
(A) f.seek(-10,1)	(I) From beginning of file, move 10 bytes forward
(B) f.seek(10,1)	(II) From current position, move 10 bytes backward
(C) f.seek(10)	(III) From current position, move 10 bytes forward
(D) f.seek(-10,2)	(IV) From end of the file, move 10 bytes backward

• (A) - (I), (B) - (II), (C) - (III), (D) - (IV)
• (A) - (II), (B) - (III), (C) - (IV), (D) - (I)
• (A) - (III), (B) - (II), (C) - (IV), (D) - (I)
• (A) - (II), (B) - (III), (C) - (I), (D) - (IV)

Answer 1

The Correct Option is 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:

(A) f.seek(-10,1)	(II) From current position, move 10 bytes backward
(B) f.seek(10,1)	(III) From current position, move 10 bytes forward
(C) f.seek(10)	(I) From beginning of file, move 10 bytes forward
(D) f.seek(-10,2)	(IV) From end of the file, move 10 bytes backward

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

Answer 2

 

Code	Interpretation	Correct Match
f.seek(-10,1)	From current position, move 10 bytes backward	(II)
f.seek(10,1)	From current position, move 10 bytes forward	(III)
f.seek(10)	From beginning of file (default), move 10 bytes forward	(I)
f.seek(-10,2)	From end of file, move 10 bytes backward	(IV)

Correct Matching:

• (A) - (II)
• (B) - (III)
• (C) - (I)
• (D) - (IV)
