You should probably add requests http://docs.python-requests.org. Anyway great list! I'm already using most of them and they are awesome.
I specifically excluded awesome libs like requests, SQLAlchemy, Flask, fabric etc. because I thought them too "main-stream". If you know what you're trying to do, it's almost guaranteed that you'll stumble over the aforementioned. I tried to compile a little bit of a list of libraries that SHOULD be better known, but aren't.
Thanks a million.
Could probably do a top 7 just by Reitz:

3. Envoy - "subprocess for humans"
4. Tablib - csv, excel and plenty others, tabular data
5. python-guide - A work in progress book
6. dynamo - Amazon Dynamo as a python dict
