\section{\module{uu} ---         Encode and decode uuencode files} \declaremodule{standard}{uu}\modulesynopsis{Encode and decode files in uuencode format.}\moduleauthor{Lance Ellinghouse}{}  This module encodes and decodes files in uuencode format, allowingarbitrary binary data to be transferred over ASCII-only connections.Wherever a file argument is expected, the methods accept a file-likeobject.  For backwards compatibility, a string containing a pathnameis also accepted, and the corresponding file will be opened forreading and writing; the pathname \code{'-'} is understood to mean thestandard input or output.  However, this interface is deprecated; it'sbetter for the caller to open the file itself, and be sure that, whenrequired, the mode is \code{'rb'} or \code{'wb'} on Windows. This code was contributed by Lance Ellinghouse, and modified by JackJansen.\index{Jansen, Jack}\index{Ellinghouse, Lance} The \module{uu} module defines the following functions: \begin{funcdesc}{encode}{in_file, out_file\optional{, name\optional{, mode}}}  Uuencode file \var{in_file} into file \var{out_file}.  The uuencoded  file will have the header specifying \var{name} and \var{mode} as  the defaults for the results of decoding the file. The default  defaults are taken from \var{in_file}, or \code{'-'} and \code{0666}  respectively.\end{funcdesc} \begin{funcdesc}{decode}{in_file\optional{, out_file\optional{, mode\optional{, quiet}}}}  This call decodes uuencoded file \var{in_file} placing the result on  file \var{out_file}. If \var{out_file} is a pathname, \var{mode} is  used to set the permission bits if the file must be  created. Defaults for \var{out_file} and \var{mode} are taken from  the uuencode header.  However, if the file specified in the header  already exists, a \exception{uu.Error} is raised.   \function{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 \var{quiet} to a true value  silences this warning.\end{funcdesc} \begin{excclassdesc}{Error}{}  Subclass of \exception{Exception}, this can be raised by  \function{uu.decode()} under various situations, such as described  above, but also including a badly formatted header, or truncated  input file.\end{excclassdesc} \begin{seealso}  \seemodule{binascii}{Support module containing \ASCII-to-binary                       and binary-to-\ASCII{} conversions.}\end{seealso}
