Hello,

The follow can be considered either a feature request or a bug and was
originally asked as question on the Emacs StackOverflow page:

<
https://emacs.stackexchange.com/questions/76257/python-mode-multi-line-conditional-indentation
>

But I'll reproduce it in full here anyways:

Given the following somewhat silly Python code with a multi-line condition:

    if ("VALUE" in my_uncessarily_long_dictionary and
        some_other_long_condition_case):
        do_something()
    else:
        pass

This is written as Emacs typically indents each line, which I'm normally
fine
with. However, quite a few linters prefer the condition to be indented
visually
different from the next (non-conditional) line, e.g., something like this:

    if ("VALUE" in my_uncessarily_long_dictionary and
            some_other_long_condition_case):
        do_something():
    else:
        pass

As was helpfully provided by Tobias in the answer to this question on
StackOverflow, this was solved on Emacs-28.1. I went ahead and refactored
and
tested it on Emacs-master and it appears to be working fine there as well.
The
code for this is attached to this email.

One noticeable caveat is that **any** parenthesis can now be additionally
indented, e.g., the follow is now also possible:

    this_is_a_tuple = (long_variable_name_here,
                                      also_a_long_variable_name)

Although, given that this can be cycled at will by the user, I'm not sure
if it
is a bad additional feature or not.

Ideally, I suppose that `python-indent-context` could be modified to add a
`:inside-cond-paren` symbol that signals that the parenthesis is for a
conditional expression and thus the extra indentation should be applied,
and not
in any other case. That does seem a bit harder for me to fix at a cursory
glance
however, so maybe this fix is enough?

Best regards,
Gustaf
