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.
