17.8 <tt class="module">py_compile</tt> --
Compile Python source files</A>
</H1>
<P>
<P>
<P>
The <tt class="module">py_compile</tt> module provides a single function to generate
a byte-code file from a source file.
<P>
Though not often needed, this function can be useful when installing
modules for shared use, especially if some of the users may not have
permission to write the byte-code cache files in the directory
containing the source code.
<P>
<dl><dt><b><a name='l2h-3059'><tt class='function'>compile</tt></a></b> (<var>file</var><big>[</big><var>, cfile</var><big>[</big><var>, dfile</var><big>]</big><big>]</big>)
<dd>
Compile a source file to byte-code and write out the byte-code cache
file. The source code is loaded from the file name <var>file</var>. The
byte-code is written to <var>cfile</var>, which defaults to <var>file</var>
<code>+</code> <code>'c'</code> (<code>'o'</code> if optimization is enabled in the
current interpreter). If <var>dfile</var> is specified, it is used as
the name of the source file in error messages instead of <var>file</var>.
