Hi,

I'm pretty new to Python, and I want to develop my first serious open source project. I want to ask what is the common coding style for python projects. I'll put also what I'm doing right now.

1.- What is the most widely used column width? (the eternal question)
I'm currently sticking to 80 columns (and it's a pain!)

2.- What quotes to use? (I've seen everything and PEP 8 does not mention anything clear)
I'm using single quotes for everything but docstrings, which use triple double quotes.

3.- Where do I put my imports?
I'm putting them at file header in this order.

import sys
import -rest of python modules needed-

import whatever
import -rest of application modules-

<code here>

4.- Can I use "import whatever.function as blah"?
I saw some documents that disregard doing this.

5.- Tabs or spaces for indenting?
Currently using 4 spaces tabs.

6.- Variable naming style? I'm using lowercase for everything but classes, which I put in camelCase.

Anything you would recommend?
