源代码： Lib/uu.py
Deprecated since version 3.11, will be removed in version 3.13: The uu 模块被弃用 (见 PEP 594 了解细节)。 base64 is a modern alternative.
base64
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。
'-'
'rb'
'wb'

The uu 模块定义了下列函数：
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.
0o666
'`'
3.7 版改变： 添加 backtick 参数。
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。
uu.Error
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.
decode()
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.
Exception
uu.decode()
