title: trigger python script everytime a file is downloaded into a specific folder
body: <p>I have a specific folder in which I download certain .zip files. I am writing a python script to automate the unzip, upload, and deletion of files from this folder. Is there a way to automatically trigger my python script each time a zip file is downloaded to this folder?</p>
