[Reprint] enable the Python auto-completion and prompt function in VIM

Reprint: http://zhongwei-leg.iteye.com/blog/941474

One of the reasons surrounding colleagues don't like using vim to write Python code is that VIM does not automatically complete and prompt like Visual Studio.
In fact, just vim is too low-key, we do not know.

Here's a look at Python omni complete, which looks like this when the installation is enabled:

1. How to install ' Python omni Complete ' plugin.

If it is VIM7.3, do not need to download Pythoncomplete.vim this plugin, because the installation comes with.
However, you must ensure that when you compile and install VIM, the Python feature is enabled, that is,

./configure--with-features=huge--enable-pythoninterp=yes

Because, Pythoncomplete.vim is written in Python.

We can see it in the Vim AutoLoad directory

ls -la /usr/local/share/vim/vim73/autoload/

If not, download the Pythoncomplete.vim and copy it to the ~/.vim/autoload/directory.

2. How to enable auto-completion
Add such two lines to the ~/.VIMRC

Set Omnifunc=pythoncomplete#complete

At this point, we have completed the installation and configuration work.

3. How to use auto-completion
For example, we enter

Import Sysprint sys.

At this point, press ctrl+x, Ctrl+o, you can see the prompt list box, as well as the corresponding docstring.
CTRL + N, ctrl+p up and down Select
ESC to cancel the prompt box.

4. Deficiencies
A. The attribute has no docstring, only functions have.
:( This seems to be a bad idea, because the attribute does not seem to docstring this concept.
B. In the absence of a drop-down box, there is no docstring
