title: ftp download file inside zip file using python
body: <p>There's a daily updated zip file of about (~600 MB), found on an ftp site, I created a script that does the following: </p>
  
  <ul>
  <li>Connect to the data ftp site</li>
  <li>Download the zip file (600 MB)</li>
  <li>Extract it to a local folder to find one or two text files insides that zip file of my interest.</li>
  </ul>
  
  <p>My question is, do I need to daily download 600MB size of zip file to get that .txt file(s), my intention is to try saving time and money. May be a library can list the contents of the zip file and then downloads only the two text files I'm interested in?</p>
