While not quite what you're asking for, vim offers an "indent text
object" plugin[1] that allows you to use a block of indentation
around the cursor as an object. So you can use vim's grammar to issue
commands like "dai" to delete the current indentation-defined block;
or you can use ">ii" to add a level of indentation to the
indentation-defined block.
If you want to make a vim mapping that will jump up to the top of the
previous level of indentation, the following should do the trick
:nnoremap <expr> Q '?^'.repeat(' ', (strlen(substitute(getline('.'), '\S.*',
'', ''))-&sw)).'\S?e'."\<cr>"
There might be some edge-cases that I haven't caught there, but, as
long as you edit with spaces rather than tabs, it should work,
including the accommodation of your 'shiftwidth', even if it's not
PEP8 4-spaces-per-indent.
