How to align second line of command with first line?

If a "def" precedes, arguments should be indented as asked for.

No, I mean within a called function, not the function arguments itself:

### Not here:
def do_something(argument1, argument2):
    ### But here:
    do_something_else(argument1,
     argument2)

I figured out that it works if I move the cursor to column 0 first. But what does it do if the cursor is right before the a of argument2? For dedent I can use backspace, tab should align the current line with the previous line.

I get the same behaviour for the function definition:

def do_something(argument1,
 argument2):
    pass

argument2 is dedented if the cursor is right before the a of argument2. Same for the alignment of "pass".

TAB is implemented to cycle possible indents. If at outmost possible indent, first TAB should do nothing, second would dedent until 0 is reached, than jump to the outmost again.

A typical case where I need the align functionality is after a function name was changed, and the new name is longer than the old name. All following lines with arguments that belong to that function now have not enough indentation.

My original question was how the alignment can be done. I mean without adding the required spaces manually. And without the TAB cycle that starts with dedent. The shortest sequence I found so far is Home+Tab. With python.el that ships with Emacs just one TAB is needed.

Call py-indent-and-forward for the remaining lines

Alternatively there are a couple of
py-mark-... commands

usable

which follow by py-indent-region

It only dedents from second TAB.
First TAB should indent unless it is at max-indent already

TAB, py-indent-or-complete, and py-indent-line dedent immediately if the cursor is not in column 0.

bolp seems to control whether outmost indent is used ("now choose the indent" in py-indent-line). That correlates with my observation that the cursor must be in column 0 to get the outmost indent. I added the case that this-command is different from last-command, now it works for me.

Not quite. They dedent immediately only if _not_ at outmost position.

Yes, that's the direction of cyling.
