The tarfile module makes it possible to read and create tar archives. Some facts and figures:
|[name[, mode [, fileobj[, bufsize]]]])|
mode has to be a string of the form
it defaults to
'r'. Here is a full list of mode combinations:
||Open for reading with transparent compression (recommended).|
||Open for reading exclusively without compression.|
||Open for reading with gzip compression.|
||Open for reading with bzip2 compression.|
||Open for appending with no compression.|
||Open for uncompressed writing.|
||Open for gzip compressed writing.|
||Open for bzip2 compressed writing.|
'a:bz2' is not possible.
If mode is not suitable to open a certain (compressed) file for
reading, ReadError is raised. Use mode
avoid this. If a compression method is not supported,
CompressionError is raised.
If fileobj is specified, it is used as an alternative to a file object opened for name.
For special purposes, there is a second format for mode:
'filemode|[compression]'. open() will return a
TarFile object that processes its data as a stream of
blocks. No random seeking will be done on the file. If given,
fileobj may be any object that has a read() or
write() method (depending on the mode).
bufsize specifies the blocksize and defaults to
512 bytes. Use this variant in combination with
sys.stdin, a socket file object or a tape device.
However, such a TarFile object is limited in that it does
not allow to be accessed randomly, see ``Examples''
(section 12.5.3). The currently possible modes:
||Open a stream of tar blocks for reading with transparent compression.|
||Open a stream of uncompressed tar blocks for reading.|
||Open a gzip compressed stream for reading.|
||Open a bzip2 compressed stream for reading.|
||Open an uncompressed stream for writing.|
||Open an gzip compressed stream for writing.|
||Open an bzip2 compressed stream for writing.|
