There are different styles, but in general they are concise, and I like them.

perl use various sigils to remain concise, while other languages take a lot of room on the screen: too many letters in the usual function names, not enough sigils within the language.

It's like if everything was in binary or hex, instead of using the full range of ASCII: while technically possible, it may be harder to fit into your head

Python has one sub-style I dislike the most: using tabs for indentation, because how much EXTRA room they use on the screen.

It must not just be me, as there are solutions for coloring the spaces (I forked https://github.com/csdvrx/indent-rainbow to focus on black-and-white and using spaces instead of tabs)

I use space to limit the issue, but I can't make python less verbose.

python isn't innocent either: I recently traced a issue where exit(0) wasn't working to a threading problem, making a bad use of atexit.

> tabs for indentation

I don’t know a single Python project that does it. You can’t mix space and tabs for indentation.

4 spaces is the default for Python formatters like black, ruff (not sure whether it is configurable—never tried to change).

Big indent is a feature—deep nesting is a code smell.

Can you not adjust your tab stops?

I hate it too, because tabs look like spaces and they have a different syntactic meaning

I can, in vim it's simple. It just bothers me that it is the default and I have to take care of tabs with the rainbow, or a toggle shortcut like:

function TabCollapse_Toggle() abort

    if &tabstop ==1

        set tabstop=8

    else

        set tabstop=1

    endif

 endfunction

BTW if you hate tabs looking like other characters and other invisible characters (like spaces at the end of line, non breaking spaces...), I have a solution in CuteVim (https://github.com/csdvrx/CuteVim : just run the portable executable) where I mapped it by default to a Fxx key

If you already use vim, here's the relevant part: assuming your Shift-F11 is free, add to your vimrc:

" Default is off, `se list` to turn on and `se nolist` to turn off

" Traditional with ISO-8859-1:

"set listchars=tab:»·space:_,trail:·,eol:¶

" Or cuter with unicodes:

set listchars=tab:↹⇥,space:_,nbsp:␣,trail:•,extends:⟩,precedes:⟨,eol:↲

set showbreak=↪

inoremap <silent> <S-F11> <Esc>:set list!<CR>

noremap <silent> <S-F11> :set list!<CR>

Shift-F11 will then become a toggle, to show you tabs: you will see ↹ where the tab starts, and ⇥ for how long it is

>Can you not adjust your tab stops?

I've used this in vim for years:

:se expandtab tabstop=4 shiftwidth=4

(those can be abbreviated, check docs)

Then:

I use only tabs for indentation.

All the tabs get expanded to four spaces each.

Indenting and unindenting lines or blocks of lines, moves them by four spaces.

Never had a problem.

Maybe there are more fancy ways, but this works fine for me.

Then Python will not work (?)

Sure it will work. Even before I discovered this method (which is simple), I was using four spaces typed manually, for indentation in Python, for years.

Maybe it is you who "will not work".

Did you try it before commenting? I already said it works fine.

e.g. for tabstop, use ts, and for shiftwidth, use sw.
