The reference_point is selected by the from_what argument. It accepts three values:
0: sets the reference_point at the beginning of the file.
1: sets the reference_point at the current file position.
2: sets the reference_point at the end of the file.
By default from_what argument is set to 0.

Default value of reference_point in Python seek() function
The seek() function in Python is used to change the position of the file handle within a file. It allows us to move the pointer to a specific location in the file so that the next read or write operation can be performed from that position.
The syntax of the seek() function is as follows:
myfile.seek(offset, reference_point)
- myfile: It is the file object on which we want to perform the seek operation.
- offset: It specifies the number of bytes we want to move the file pointer. The offset can be both positive and negative. Positive offset moves the pointer forward, while negative offset moves it backward.
- reference_point: It indicates the reference point from where the offset is calculated. It can take three values: 0, 1, or 2.
Now, let's discuss the default value of the reference_point.
Default value of reference_point:
The default value of the reference_point in the seek() function is 0.
- The reference_point 0 represents the beginning of the file. When we specify an offset and use reference_point as 0, it means we want to move the file pointer 'offset' number of bytes from the beginning of the file.
For example, if we want to move the file pointer to the 10th byte from the beginning of the file, we would use the seek() function as follows:
myfile.seek(10, 0)
Here, the offset is 10, and the reference_point is 0, indicating that we want to move the file pointer 10 bytes forward from the beginning of the file.
Therefore, the correct answer is option 'a) 0', which represents the default value of the reference_point in the seek() function.
