Python-mode VS vim-textobj-python

As for the Vim auto complete plug-in to use. The biggest (and rather quite bloated provider) are coc and youcompleteme. Vim had countless other completion provider plugins over the years, I lost track of which ones are still good to use and which ones should already be superseded by better techs, but one I personally use python-mode, which uses rope and vim-lsp which supports pylsp.

python-mode plugin works well as an IDE-like solution: https://github.com/python-mode/python-mode

If you're happy with a plugin, pymode (https://github.com/python-mode/python-mode) is worth a look. Map running to r (or whatever works for you) makes running easy. End result is IDE-like.

If you want a quick start to building Vim based IDE for Python, I recommend python-mode. It gives you most of the things you're going to need in one plugin, there are often better implementations of some of its features in other more specialised plugins, but if you don't have time to research and learn to integrate a lot of different plugins, it's a great base to start from. Over time as you learn how you prefer to work and found specialised plugins that suits your workflow better, you can disable many of its features and replace them with more specialised plugins.

I also highly recommend python-mode for Python refactoring using python-rope. It supports variable/function/class renaming, extract method/local variable, variable/method inlining, adding/removing/rearranging parameters from method signature, removing unused and duplicate imports, and many other useful code transformations.

However, adding all these things by hand takes time. I only know python so that's what im using vim for, and i tried out pymode, but that's way too many features introduced at once. For this reason I've also avoided using others configurations.

Eg for python (there are several others) https://github.com/python-mode/python-mode

There is a plugin called python-mode. This adds syntax highlighting and many other features to your vim.

Update that tool to work with Python. For example, Python-Mode.

For Python, for example, I use https://github.com/bps/vim-textobj-python.

vim-textobj-python and having language aware text-objects are also very useful, especially when Slime-ing code to the REPL.

Out of the box, vim is already very good at text editing, but to supercharge your editing power, you would want to add some additional text objects. Most important for Python is bps/vim-textobj-python and kana/vim-textobj-indent.

Also, for general text editing in vim, you want to have useful text objects that understands the language that you're working on. For python, I found these the most useful from my collection: bps/vim-textobj-python (function/class text objects), pianohacker/vim-textobj-indented-paragraph (indentation text objects).
