Python script to download and unzip file

I have been trying to figure this out for while. I have a remote zip file that contains a .txt file. I need to download and parse some of the data.

Which is another question. When I get the .txt file is it possible to parse the data out of it? it is organized in columns, I basically need to eliminate some of the columns.

I know this post is ambiguous, but any help would be appreciated.

Thanks for any help.

Why would you do this with python?
