Most likely, your project directory layout will also be the layout of the application when you deliver it to the user. It thus serves a dual purpose: facilitating development and deployment. For deployment, see <A href="index.lxp@lxpwrap=c8349_252ehtm.htm">Chapter 26</A>. </P><P>Over the last decade, a standard project layout has grown to maturity for open source projects. This layout consists of a toplevel directory that contains README's, installation instructions, and directories for documentation, data and source code.</P><P>A Python project often consists of several modules: one for your document classes, one for custom GUI widgets and one for the application classes, and one for scripts needed to create database definitions. For example:</P><DIVCLASS="MEDIAOBJECT"><P><DIVCLASS="CAPTION"><P>The toplevel directory layout of a large project</P></DIV></P></DIV><P>Here, the <TTCLASS="FILENAME">datamodel</TT> directory contains SQL scripts to create the database. The directory <TTCLASS="FILENAME">dbobj</TT> contains a module which handles database access. The directory <TTCLASS="FILENAME">dialogs</TT> contains designer .ui files. The directory <TTCLASS="FILENAME">html</TT> contains the application documentation in html format - it would be better to write the documentation in docbook and automatically generate html and pdf versions of the manual. Finally, the <TTCLASS="FILENAME">kuraapp</TT>, <TTCLASS="FILENAME">kuralib</TT> and <TTCLASS="FILENAME">kuragui</TT> directories are Python modules (that will have to be put on the Python path) for the application, document and custom widgets needed for this application. <TTCLASS="FILENAME">notes</TT> contains implementation notes and <TTCLASS="FILENAME">pixmaps</TT> graphics needed for the toolbar. The rest of the files speak for themselves: starter scripts for Windows and Unix, and various standard files, like <TTCLASS="FILENAME">INSTALL</TT> and <TTCLASS="FILENAME">CHANGELOG</TT></P><P>In contrast with Java application, it is not wise to nest Python modules — keeping the structure relatively flat makes it easier to import modules into each other.</P><P>Generally, Python applications start out very simple, with just one script file, and then blossom out in modules and directories. The development of the codebase in this part is a lively demonstration of that fact.</P></DIV><DIVCLASS="NAVFOOTER"><HRALIGN="LEFT"WIDTH="100%"><TABLESUMMARY="Footer navigation table"WIDTH="100%"BORDER="0"CELLPADDING="0"CELLSPACING="0"><TR><TDWIDTH="33%"ALIGN="left"VALIGN="top"><A accesskey="P" href="index.lxp@lxpwrap=x4760_252ehtm.htm">Prev</A></TD><TDWIDTH="34%"ALIGN="center"VALIGN="top"><A accesskey="H" href="index.lxp@lxpwrap=book1_252ehtm">Home</A></TD><TDWIDTH="33%"ALIGN="right"VALIGN="top"><A accesskey="N" href="index.lxp@lxpwrap=c4807_252ehtm.htm">Next</A></TD></TR><TR><TDWIDTH="33%"ALIGN="left"VALIGN="top">Macro languages</TD><TDWIDTH="34%"ALIGN="center"VALIGN="top"><A accesskey="U" href="index.lxp@lxpwrap=c4631_252ehtm.htm">Up</A></TD><TDWIDTH="33%"ALIGN="right"VALIGN="top">Actions: menus, toolbars and accelerators</TD></TR></TABLE></DIV></BODY></HTML> </td> </tr> </table> </td> </tr> </table> ⌨️ 快捷键说明
