uu
— 编码和解码 uuencode 文件
¶
源代码: 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'
在 Windows。
This code was contributed by Lance Ellinghouse, and modified by Jack Jansen.

Uuencode file

as the defaults for the results of decoding the file. The default defaults are taken from

¶
This call decodes uuencoded file
in_file
placing the result on file
out_file
。若
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
被引发。
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.
