首先，写Python代码的IDE有许多，呵呵，至于功能强大的肯定是Eclipse + pydev了，以下是pydev的显著的特性：
Some feature-highlights
- Rename refactoring: renames all occurrences for some token in your workspace -- with preview and undo/redo (1.2.6)
- Support for python 2.5 (1.2.3)
- Mark Occurrences is able to highlight all the occurrences of some token in a file (1.0.7)
- Rename Occurrences: renames all the occurrences of some token in a file (Ctrl+2+R -- 1.0.7)
- Interactive Console binded to the Pydev Editor (1.0.4)
- Open Definition Quick-outline (1.0.3)
- Debug console (1.0.2 -- allows interactive probing in suspended mode)
- Code completion with auto-import
- Code analysis (PyLint replacement, but much faster)
- Quick-Fix for problems found in code analysis
- Go to definition (Bycicle Repair Man replacement, but much more reliable)
- Debug server (allows debugging scripts not lauched from within Eclipse)
- Keywords presented as auto-completions as you type
- Quick-outline
接着，我选择使用Django框架做Web开发的话，怎么能少了对HTML, CSS, JavaScript的编辑器呢?呵呵，同样是Eclipse的插件：Aptana ，强大的智能提示，肯定帮助我们加快开发的速度和提高开发体验的（呵呵，我们也要良好的用户体验喔）。
最后不用说，就是SVN，Eclipse的SVN插件：subclipse，这样3样工具，足够了。
PS: 还有可选的，UML建模工具：EclipseUML；Mylyn: http://www.eclipse.org/mylyn/downloads/
