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
.
