Change the stream position to the given byte offset. The offset is interpreted relative to the position indicated by ``whence``. Arguments: offset (int): the offset to the new position, in bytes. whence (int): the position reference. Possible values are: * `Seek.set`: start of stream (the default). * `Seek.current`: current position; offset may be negative. * `Seek.end`: end of stream; offset must be negative. Returns: int: the new absolute position. Raises: ValueError: when ``whence`` is not known, or ``offset`` is invalid. Note: Zip compression does not support seeking, so the seeking is emulated. Seeking somewhere else than the current position will need to either: * reopen the file and restart decompression * read and discard data to advance in the file rNegative seek position {}Positive seek position {}+Invalid whence ({}, should be {}, {} or {}))intr currentr/set ValueErrorformatendr.r+r2r5r>r?)r3offsetwhence_whences r7seekz_ZipExtFile.seekQs<&kG$,,&$))#$,,&'TXX*=A:$%@%G%G%OPPDHH$A:$%@%G%G%OPP$))# AHH4<<  !))..3 IIftyy( )99 r8c0t|}|j}|tjk(r|dkrt dj ||tj k(r"||zdkrt dj ||tjk(r|dkDrat dj |t dj |tjtj tj|jj||S)aChange stream position.

There are two ways to open a `ZipFS` for the use cases of reading a zip file, and creating a new one. If you open the `ZipFS` with ``write`` set to `False` (the default) then the filesystem will be a read-only filesystem which maps to the files and directories within the zip file. Files are decompressed on the fly when you open them. Here's how you might extract and print a readme from a zip file:: with ZipFS('foo.zip') as zip_fs: readme = zip_fs.readtext('readme.txt') If you open the `ZipFS` with ``write`` set to `True`, then the `ZipFS` will be an empty temporary filesystem. Any files / directories you create in the `ZipFS` will be written in to a zip file when the `ZipFS` is closed. Here's how you might write a new zip file containing a ``readme.txt`` file:: with ZipFS('foo.zip', write=True) as new_zip: new_zip.writetext( 'readme.txt', 'This zip file was written by PyFilesystem' ) Arguments: file (str or io.IOBase): An OS filename, or an open file object. write (bool): Set to `True` to write a new zip file, or `False` (default) to read an existing zip file. compression (int): Compression to use (one of the constants defined in the `zipfile` module in the stdlib). temp_fs (str or FS): An FS URL or an FS instance to use to store data prior to zipping. Defaults to creating a new `~fs.tempfs.TempFS`.
