I wasn't suggesting it was the only way things could be done. Just
pointing out that there is enough common practice out there to suggest
that white space around infix operators is often the preferred way of
doing things. Quoting from PEP 8:

If operators with different priorities are used, consider adding
whitespace around the operators with the lowest priority(ies). Use
your own judgment; however, never use more than one space, and always
have the same amount of whitespace on both sides of a binary operator.

Yes:

i = i + 1
submitted += 1
x = x*2 - 1
hypot2 = x*x + y*y
c = (a+b) * (a-b)

...

My point is that accommodating white space around the + or - sign
isn't altogether unreasonable.

Maybe PEP 8 needs to be tweaked with an example of good complex
literal practice?
