<h1>Making executable Windows programs<a class="headerlink" href="#making-executable-windows-programs" title="Permalink to this headline">¶</a></h1>
<p>The <cite>py2exe</cite> Python library is an extension to Python <cite>distutils</cite> module which
converts Python scripts into executable Windows programs, able to run without
requiring a Python installation.</p>
<p>Making such an executable program may be a non trivial task when the script
dependencies include libraries with data or extensions, such as <cite>PyQt4</cite> or
<cite>guidata</cite> and <cite>guiqwt</cite>. This task has been considerably simplified thanks to
the helper functions provided by <tt class="xref py py-mod docutils literal"><span class="pre">guidata.disthelpers</span></tt>.</p>
