Sharing a bit useful command.

I like Pythonista on iPad or iPhone retina display.
It looks very beautiful and is very very powerful.
So I use Pythonista as my default (programming)editor.
I wrote some command script to speed up my editing(for debugging).
And others may do the same thing.
I think Pythonista users have own useful command.
I think There is a lot of useful command that is not shared.

Anyway I wrote a bit useful command script.
The script summary, example and source code are following.

Summary

Command Name : Insert string
How it works : See the example below

Example

Inserting 'XXX' to selected colnumn.

aaaaa
bbbbb
ccccc
->
aaXXXaaa
bbXXXbbb
ccXXXccc

Source code

Here

That's all.
But I want a template Markdown for sharing command script such like this.

Sorry for my bad English skill.
Thanks.
