Question

Consider the following code :

f = open ("mytry", "w+")

f.write ("0123456789abcdef")

f.seek (-3,2)  //1

printf.read(2)  //2

Explain statement 1 and give output of 2.

Answer 1

Statement 1 uses seek()method can be used to position the file object at particular place in the file. It's syntax is: fileobject.seek(offset [, from_what]).

So,f.seek(-3,2) positions the fileobject to 3 bytes before end of file.

Output of 2 is: de (It reads 2 bytes from where the file object is placed.)
