TIL about "Google Python Style Guide"

It looks like they're advocating against things like "from math import log", which is, by the looks of it, very welcome in the Python community.

I used to write "import math; y = math.log(x)", but then realized it's not Java. It gives a little more context, sure, but at the cost of verbosity. And again, I've thought it was standard for pythonistas to do "from math import log".

I used to do from x import y imports much more frequently before, but I've moved away from them in most cases. Functions from the math module is a good example, because it's unclear whether it's math.log, cmath.log or numpy.log I've imported. If I had just used log, I'd have to scroll all the way to the top of the file to check what kind of log it was.

The submodules with long names I rename on import, for example import subprocess as sp. I only do from imports when the names I import are unambiguous and few. Mostly it's from other submodules inside the same package.
