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.

uu 模块定义了下列函数:

uu. encode ( in_file , out_file , name=None , mode=None , * , backtick=False )

uuencode 文件 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 ,或 '-' and 0o666 respectively. If backtick is true, zeros are represented by '`' instead of spaces.

3.7 版改变: 添加 backtick 参数。

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 。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.

exception uu. Error

子类化的 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.
