You should attack this by breaking large expressions into smaller ones and
factoring out some of your code into helper functions.

Useless? You get a SyntaxError, remove the offending whitespace, and that's
it.

Did you know that there already is a pythonic alternative that works well in
most cases? An open (, [, or { will allow you to continue on the next line,
e. g.
items = [(foo(item), bar(item))
for row in rows
for item in row if baz(
alpha=1,
beta=item)]
no strings attached.
