I'm trying to download (using urllib.urlretrieve) a remote file into my application. It's a zip file containing an IP-to-country lookup table. I want to download the zip to the application's file system (probably 'uploads'), unzip it, process the csv and then import the sanitised data into my ip-to-country database (using import_from_csv_file).
How should I specify/access locations in the filesystem?
