If I know I want just one thing from x, I tend to use latter.
I also like 'import xyzlib as x'

Namespace get cluttered, not dirtied.  In any case, either 'x' or 'a' 
gets added.  One new name either way.

Use 4 spaces instead of 5 for indents

As Steven said, usually no

'\' causes no indentation

Beyond that, consider find a style you like.  I agree with Stvhen about 
using 'thought-sized' expressions.
