Is it possible without any plugins?
Or what's the best plugin for edit python file?
If your function is long or has many blank lines, using v}}...}}d is pretty slow.
The quickest way I've found (without plug-ins) is zc2dd. The command zc closes the fold under the cursor, so if you are at the function declaration or any line at the outermost indent level, the whole function will fold. Then 2dd (or 3dd if you have two blank lines before/after your function) will remove the whole thing.
what's the fastest way to select a function of Python via VIM?
