Python in a Nutshell

Name

seek

Synopsis

                        f.seek(pos,how=0)

Sets f’s current position to the signed integer byte offset pos from a reference point. how indicates the reference point: when how is 0, the reference is the start of the file; when it is 1, the reference is the current position; and when it is 2, the reference is the end of the file. When f is opened in text mode, the effects of f .seek may not be as expected, due to the implied translations between os.linesep and \n. This troublesome effect does not occur on Unix platforms, nor when f is opened in binary mode, nor when f .seek is called with a pos that is the result of a previous call to f .tell and how is 0. When f is opened in mode 'a' or 'a+', all data written to f is appended to the data that is already in f, regardless of calls to f .seek.
