将Emacs打造成强大的Python代码编辑工具

(setq interpreter-mode-alist

 (cons '("python" . python-mode)

 interpreter-mode-alist))

(autoload 'python-mode "python-mode" "Python editing mode." t)

;;; add these lines if you like color-based syntax highlighting

3.操作
1).执行:C-c C-c，这样会在新的窗口及缓冲区执行脚本；
2).C-j:以相同的缩进插入新的一行；
3).C-M-a:跳至函数或类首；
4).C-M-e:跳至函数或类尾；
5).C-c C-w:运行PyChecker进行代码检测；
大体的使用方式就是这样的了，另外，还有许多类或函数的模板可以通过快捷键进行，在今后常用的时候会加强了解的。感谢你能看到这里!

安装扩展
在Emacs中，通过各种扩展，打造强大的Python IDE环境，包括Snippet工具，智能提示，自动补全，重构工具，调试以及GAE的调试，等等。以下各工具的安装前提是你对Emacs的配置文件有一定的了解，所有相关的el文件都必须放在load_path能够加载的地方。

1. YASnippet
snippet工具，可自定义一些模板，必不可少的好东西！看了下面这个很酷的演示动画就明白了：
http://yasnippet.googlecode.com/files/yasnippet.avi

安装方法：

(require 'yasnippet)
(yas/initialize)
(yas/load-directory "~/.emacs.d/plugins/yasnippet-0.6.1c/snippets")
