Question
How do you change the file position to an offset value from the start? fp.seek(offset, 0) fp.seek(offset, 1) fp.seek(offset, 2) None of the above
Solution
The correct answer is fp.seek(offset, 0).
Here's the step-by-step explanation:
-
fp.seek(offset, 0)is used to change the file position in Python.fpis the file pointer you're working with andseek()is a method that sets the file's current position. -
The
seek()function takes two parameters -offsetandfrom_what. Theoffsetis the number of positions to move forward from thefrom_whatposition. -
If
from_whatis 0, it means the offset is calculated from the beginning of the file. Sofp.seek(offset, 0)will move the positionoffsetnumber of positions from the start of the file. -
fp.seek(offset, 1)would move the position from the current position andfp.seek(offset, 2)would move the position from the end of the file. Therefore, these are not correct if you want to move the position from the start of the file.
So, the correct way to change the file position to an offset value from the start is fp.seek(offset, 0).
