uu — Encode and decode uuencode files¶
Source code: Lib/uu.py
Deprecated since version 3.11, will be removed in version 3.13: The
uu module is deprecated
(see PEP 594 for details).
base64 is a modern alternative.
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
'wb' on Windows.
This code was contributed by Lance Ellinghouse, and modified by Jack Jansen.
uu module defines the following functions:
- uu.encode(in_file, out_file, name=None, mode=None, *, backtick=False)¶
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
0o666respectively. If backtick is true, zeros are represented by
'`'instead of spaces.
Changed in version 3.7: Added the backtick parameter.
- 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
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.
- exception uu.Error¶
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.
Support module containing ASCII-to-binary and binary-to-ASCII conversions.
