What is the purpose of seek() function?

Answer:

The seek( ) method is used to position the file object at a particular position in a file. 

The syntax of seek() is: 

file_object.seek(offset , [reference_point])

In the above syntax, 

• offset is the number of bytes by which the file object is to be moved . 
• reference_point indicates the starting position of the file object . That is, with reference to which position, the offset has to be counted. 

It can have any of the following values:

• 0 - beginning of the file 
• 1 - current position of the file 
• 2 - end of file  
• Default value of reference_point is 0.
