As we all know that now vim also supports auto-completion for many languages which includes Python too. And if you use vim as a python ide then most probably you will also want the relative functions to pop out as soon you type dot "." so that you don't have to remember them ;) .
So here is quick guide on how to set up your vim for autocompletion of your python codes in case it is not already enabled.
First try this :
a=[1,2,3]
a.
After typing the above lines press "ctrl+x" then "ctrl+o" , if this pops up a menu showing the methods which can be used then you dont need to read further and just enjoy your coding :) .
In case you dont find anything happening then go through the following steps:
1> Type:
vim --version | grep "system"
It should show you something like this:
[root@Rogue codes]# vim --version | grep "system"
system vimrc file: "/etc/vimrc"
So your vim configuration file is in /etc/
2.> Now open it for editing.
It will be better if you make a backup of this file before editing it.
Now type:
vim /etc/vimrc
3.> In the file opened add the following lines in top of the file:
autocmd FileType python set completefunc=pythoncomplete#Complete
Now save it.
Open a python file and try to do the previous thing again that is:
a=[1,2,3]
a.
Now press "ctrl+x" then "ctrl+o" , if this opens the autocompletion window then you are in the right track.
Now for something extra:
It is quite a waste of keyboard strokes to type ctrl+x then ctrl+o, so lets map it to the most easiest thing, i.e. to "." itself.
Again open the vimrc file and add the following line to it:
autocmd FileType python imap . .<C-x><C-o>
after imap there is a space then a "." then a space then again a "." and <C-x><C-o>
Here we are saying that as soon as you press a dot then first type a dot and then press ctrl+x then ctrl+o.
The reason for putting a dot before <C-x><C-o> is that the dot now becomes a map to the sequence of key-strokes, so when you press a dot it is not taken as an input but is rather placed with the given sequence.
Now you just need to press "." and the auto-completion will pop out.
Have fun.
