uu — Encode and decode uuencode files¶Source code: Lib/uu.py
This module encodes and decodes files in uuencode format, allowing arbitrary
binary data to be transferred over ASCII-only connections. Wherever a file
argument is expected, the methods accept a file-like object. For backwards
compatibility, a string containing a pathname is also accepted, and the
corresponding file will be opened for reading and writing; the pathname '-'
is understood to mean the standard input or output. However, this interface is
deprecated; it’s better for the caller to open the file itself, and be sure
that, when required, the mode is 'rb' or 'wb' on Windows.
This code was contributed by Lance Ellinghouse, and modified by Jack Jansen.
The uu module defines the following functions:
uu.encode(in_file, out_file, name=None, mode=None)¶Uuencode file in_file into file out_file. The uuencoded file will have
the header specifying name and mode as the defaults for the results of
decoding the file. The default defaults are taken from in_file, or '-'
and 0o666 respectively.
uu.decode(in_file, out_file=None, mode=None, quiet=False)¶This call decodes uuencoded file in_file placing the result on file
out_file. If out_file is a pathname, mode is used to set the permission
bits if the file must be created. Defaults for out_file and mode are taken
from the uuencode header. However, if the file specified in the header already
exists, a uu.Error is raised.
decode() may print a warning to standard error if the input was produced
by an incorrect uuencoder and Python could recover from that error. Setting
quiet to a true value silences this warning.
uu.Error¶Subclass of Exception, this can be raised by uu.decode() under
various situations, such as described above, but also including a badly
formatted header, or truncated input file.
