downloading a CSV

[noydb]

Greetings All,

Python v 3.4, windows

I want to be able to download this CSV file and save to disk
>> http://earthquake.usgs.gov/earthquakes/feed/v1.0/summary/all_month.csv 

This (interacting with the web using python) is very new to me, so can anyone provide direction on how to go about doing this?  Is it involved?  Is there a good example out there that can illustrate the needs/mechanics/how-to?

Many thanks in advance!
