如果您使用的是VIM版本8+，只需键入Ctrl + n或Ctrl + p。

在插入模式下，使用Ctrl-N获取单词建议列表。键入:help i_CTRL-N以查看Vim关于此功能的文档。

下面是一个将Python字典导入Vim的示例。

你可以使用像AutoComplPop这样的插件在你输入的时候自动完成代码。

2015编辑:我个人现在使用YouCompleteMe。

I recently discovered a project called OniVim, which is an electron-based front-end for NeoVim that comes with very nice autocomplete for several languages out of the box, and since it's basically just a wrapper around NeoVim, you have the full power of vim at your disposal if the GUI doesn't meet your needs. It's still in early development, but it is rapidly improving and there is a really active community around it. I have been using vim for over 10 years and started giving Oni a test drive a few weeks ago, and while it does have some bugs here and there it hasn't gotten in my way. I would strongly recommend it to new vim users who are still getting their vim-fingers!

我已经使用neocomplcache大约半年了。它是一个插件，在你所有的缓冲区中收集单词缓存，然后为你提供它们来自动补全。

在前面的链接中，项目页面上有一组截图。Neocomplcache还有大量的配置选项，在项目页面上也有基本的示例。

如果您需要更深入的内容，您可以在我的vimrc中查看相关部分-只需搜索单词neocomplcache。
