Multi-line conditionals etc.: PEP-8 explicitly says to break after a binary operator instead of before it. I'm afraid that I cannot see the appeal of that. It makes a lot more sense to me to break before the conditional, so that in wrapped/continued lines, each sub-line begins with the conditional:
if (condition1 \
or condition2 \
or condition3):
do_something()
As can be seen, I also like to add an extra indent for the sublines, so that they are visually offset from the block below. PEP-8 does not say anything explicit about this (does it?), but the examples have the sub-lines lining up with the opening parentheses.
