python: import function

This is interesting to me. We can import only a particular function of a module inside python

Say there is a function boto.ec2.regions()

So I would write

>>> import boto.ec2
or
>>> from boto import ec2

>>> boto.ec2.regions()
or
>>> ec2.regions()

But we can also write

>>> from boto.ec2 import regions

>>> regions()

I had this scenario. Inside my python file I had import my util file. In the util file I had the above import.

from boto.ec2 import regions

So in my python file I could write

import util

util.regions()

Awesome right??
