I don't believe PEP 8 requires whitespace around all binary operators.
Where do you read that?
Quoting from http://www.python.org/dev/peps/pep-0008/#other-recommendations
(with elision):
Use spaces around arithmetic operators:
No:
i=i+1
submitted +=1
x = x*2 - 1
hypot2 = x*x + y*y
c = (a+b) * (a-b)
End quote.
I agree that this could be reworded. Especially when the operands are
as short as in the examples, the last three "No"s read better to me than
the "Yes" entries. In this case, spacing serves for visually grouping
expressions by precedence, which otherwise could also be indicated by
(semantically unnecessary) parens.
But in all cases discussed here, PEP8 should not be seen as a law.
Its second section ("A Foolish Consistency is the Hobgoblin of Little
Minds") is quite prominent for a reason.
