add a new line with the same indentation level as the current line

Question

when python code block gets larger, it's hard to find the right indentation level

def foo():
    for a in l:  # l1
    # l1-1
        for b in k: # l2
            print(a)
        # (2)
    print(b)
    # (1)

suppose I have my cursor at the first for (l1 line) , then I would insert a new line at # (1) and move cursor there similarly from # l2 to # (2)

I found similar solution https://superuser.com/q/1017094/309229 but it navigates only, it doesn't let me create a new line.

Does this answer your question: https://emacs.stackexchange.com/questions/30363/mapping-ret-to-use-the-same-indentation-level-as-the-previous-line?rq=1? — Manuel Uberti, Aug 04 '23 at 13:57
@ManuelUberti thanks, but it seems it goes from #l1 to #l1-1 not # (1) — eugene, Aug 04 '23 at 14:29

It may be not accepted by usual Python standards. See the picture below and note the error [E115]. (the `:' introduce an indented block)

This is automatically corrected if you add the apheleia package to your init.el and add the Python module black to your installation, which is a code format utility. See the picture below.

As for indentation guides, the package highlight-indent-guides may help you - the character ?\x2502 draw a tiny vertical line, as in posted pictures.

(use-package highlight-indent-guides
  :defer t
  :hook (prog-mode-hook . highlight-indent-guides-mode)
  :init
  (setq highlight-indent-guides-method 'character
        highlight-indent-guides-character ?\x2502)
  (highlight-indent-guides-mode 1))

add a new line with the same indentation level as the current line
